Backpack Sizing Guide
Sizing & Fit
This fastpack is designed to be worn higher and tighter than our original Kumo. For this reason, the back length for S/M is 16" and 18" for M/L. Please keep this in mind when selecting your size.
Torso length:
Start at the C7 vertebra at the base of your neck. The best way to find this is to bend your neck and feel the first bump along the base of your neck. This bump is where you will want to start your measurement.
Next, you'll want to find the midpoint between your iliac crest. To find your iliac crest, cup your hipbones on both sides and find the center point on your spine. This midpoint is where your thumbs should be pointing.
Finally, you'll need help measuring from the C7 vertebra to your iliac crest. From there, you'll have your torso measurement.
S/M: 16" - 14" - 20" torso
M/L: 18" - 16" - 23" torso
If you're in between sizes, you will want to
+ Size down for more of a shoulder wrap and higher hipbelt
+ Size up for a lower hipbelt fit

Used the Fast Kumo on the Camino Frances and Camino Finisterre-Muxia in Jun-Jul 26. 610 miles and 42 days! Backpack help up great. Zero issues except for getting dirty. Very comfortable. I was at about 15 pounds with a liter and a half of water. The front water bottle pockets are great. They each hold a 500ml plastic water bottle. Re-use the bottle until it wears out and then buy new ones. Used the top lid zipper compartment for paperwork. The front hip pockets were great for electrolytes, buff, hiking gloves, etc. Small pocket by the shoulders strap water bottle holder for powerbars. Pack was just the right size. I used some of those twisty straps that hold their shape to hold the top of my hiking poles when not using them. The poles worked better in the side pockets because the hiking poles carry strap with the slide at the bottom was not long enough, it was difficult to put them there. The side straps held a poncho or fleece. The very stretchy back pocket held my Keen sandals I used at night or on rest days, and it retained its stretch well. It was fine being frameless and the back pad was comfortable. I was concerned how small the clips were on it, but they held up fine. I had a pound advantage over my wife's 34L Osprey just in pack weight. Weight matters on the Camino when you are in your 60s! I will use this pack again on my next adventure hike!
I used this pack for my 2025 PCT thru-hike. It was a good pack for me and held up the whole way thru, but is falling apart now. I did use the pack in the Sierras with a BV500 bear canister inside the pack, for the ~400 miles where canisters were required (a tight fit, but it worked!). My favorite feature was the pad sleeve. I swapped out the sit pad for my shortened closed-cell foam sleeping pad. I'd love to see more sizes offered since the S/M size was almost too big on me. Fortunately, the Gossamer folks at PCT Trail Days helped me find a workaround to swap in a different, smaller hipbelt. Thanks, guys!
This pack is the perfect size for a kid aged 7 - 12. My 12-year-old has been using it for the hundreds of miles on Colorado Trail, 14ers, and the Camino Frances for 5 years now. He says he has no plans to upgrade!
Got this pack for an FKT attempt of the Sangre de Cristo mountains. Absolutely insane how well it carried with everything I needed for 4 days, not only while walking, but climbing, running, graciously falling down steep scree slopes and weaving through mazes of blowdowns. Honestly changed my prospective of what a comfortable pack light weight pack can be and can’t wait to take it out for many many more adventures and hopefully another shot at the Sangres FKT. Thanks Gossamer gear!
I've been loving the Kumo fastpack as my do everything backpack-- day hikes and travel. I particularly appreciate how all the pockets allow me to easily access everything I need to have on hand while moving. However, a 2 night backpack of the Timberline Trail showed me where it really shines. I started with a total weight of about 16 lbs, and it carried so nicely I didn't miss my Gorilla at all! I was surprised at how comfortable it was, given it's frameless and I don't like weight on my shoulders. I took less and although maybe I didn't do more, I certainly enjoyed the journey more!
Love the simplicity of this pack! As a runner I'm used to having the front access pockets and not sure why other packs do not offer this. I do wish there was a strap over the top to be able to hold a bear cannister instead of the top flap which isn't super functional.
Ideal bag for the Camino de Santiago. The Zumu became my best buddy for 32 days of walking the French Way. Did everything I needed!
Overall I’m berry happy with this pack. It carries the weight well and fits great whether it’s loaded for a day trip or if I have enough gear to spend an unexpected night outside (~10lbs). The running vest harness distributes the weight great and I find this pack more comfortable than other with a load-bearing hip belt. I’m happy with the adjustable storage space with the top entry & there’s a good amount of expandable stretch to the front and side pockets. 2 areas for improvement are the front water bottle pockets aren’t the same size. The trash pocket cuts into to bottle pocket size, so you either need to carry a smaller flask or deal with being uneven. Seems like the trash pocket could ride over top of the bottle. The other area for reconsideration is the basement of the SPOt attachment strap. It’s so far up the harness my InReach Mini flops around and hits me in the face. I ended up moving it so it’s attached to the emergency whistle loop & stored in the outer right harness pocket. Customer service is amazing. My pack arrived without the side compression cording. I alerted GG right away and they had a whole new packet out to me and it arrived in a few days. Quick interaction, no hassle. Thanks y’all!!
Perfect! Thank you
Used the Kumo Fastpack on a 5 day trip on the foothills trail. Total weight was 22 lbs including a BV450 bear vault. This pack is the most comfortable i have ever hiked with. The wide shoulder straps distributed the load well. The pack fit well on my back and never shifted. This is now my goto pack for multiday hikes in the 5 day range.
Very nice pack. Hope it lives up to the hype.
My first Gossamer pack was the Mariposa 60. I have made two 10 day trips on the AT and that is the best pack I’ve ever used. I am heading to Europe in a few weeks and needed a day pack for touring around Europe so I bought the Fast Kumo 36 Fastpack. It looks like I will be satisfied with this pack just like the Mariposa 60 so I’m excited to use it soon.
Surprised to know that the bag doesn't have a separate pouch for the water bladder.
I got this bag to use in a 5 day expedition adventure race in Tasmania and all up I'm very happy with it. I love the vest style harness and accessible pockets. I found the bag to be comfortable and the removable sit pad came in useful on a number of occasions when we had to just lay down and sleep on the forest floor. My only negative is the pocket on the top right of the shoulder strap which is really tight to get into. With a struggle I can get a lip balm in, but getting it out again isn't easy. It needs to be a bit more stretchy to allow easier access, otherwise it's pointless. Aside from that, I'd have liked a fabric strip with a popper to hold a hydration bladder, rather than the short stubby loop that requires a karabiner to hold a bladder up. Also still trying to figure out how to secure poles to the back of the pack - there are loops to hold the bottom but nothing to hold the top...
I absolutely love this pack. It fits my short torso perfectly. Yet to perfect the “be bold, start cold” mantra, I love the fact that I can easily stow away my gloves, hat, jacket, and any other layer I need to shed in the main compartment. As a Hike Leader, I usually carry the “stuff” others don’t. This pack holds it all and feels great on. My only wish is that the opening for a hydration tube was wider. Yes, I do use a water bladder. I’m going to have to enlarge that opening somehow…and scissors will be involved.
I like this pack - mostly. Everything feels just a little too small. I like the shoulder strap pockets but they are too tight. The chest strap is barely long enough to connect to the other strap (I'm not massive), the buckles and connectors are just too tiny and seem precious. The hiking pole holders are pointless. without a top constraint. I ended up carrying my poles in my hands. The hip belt pockets can't carry much, and the top pocket is nearly useless - suitable for a map or two. This needs a re-design. I may not use it again for fastpacking -opting instead for one of my ultimate direction fastpacks - but will use it for something. I do somehow like the pack - it just wasn't suitable for multi-day hut to hut hikes in the Slovenian alps. Again, this needs a re-design.
Looks like my not-so-favorable review has been removed, but I had a copy. I’ll be taking my BD D22 on an Everest Base Camp Trek. —— After falling in love with running vest packs, including a Black Diamond Distance 8L and 22L, I needed something a little bigger for my KMJ trek (25-35L). I really only found this pack to meet the needs. Key of interest are the shoulder strap pockets and the use of a chest harness to not have a waist belt. This pack is light and I like the water bottle holders on the side, particularly for winter hiking, which the BD Distance packs don't have. I didn't find the side-entry water bottle access helpful, just from the top. The Fast Kumo also has a grey body which makes it easier to find stuff over the BD pack's black body. The shove-it pouch is handy and can be used without taking the pack off. The hydration mount system is abysmal. It is just a loop. I had to get a carabiner and strap to mount my Gregory bladder and would expect the same for others. I heavily used the zippered pouch at the top. The chest harness isn't great. It doesn't carry the weight that well. It may be due to the padding. I found myself lifting the bottom of the pack up occasionally to take the strain off my shoulders. Most days I had between 8-12 pounds in my pack. The pack collar can extend high and hold alot - nearly all of the time I had cinched the straps all the way down, sometimes I couldn't get it as far down as I wanted. While it felt roomy, I don't think it can really handle the weight of being full, circa 20 pounds. I used the waist belt once. I'm not sure of the purpose. It can keep the pack in place(?), but doesn't take any weight off and makes it feel more like a regular pack. I guess the belt affords you two more zippered pockets. I much preferred to wear the Gossamer Gear fanny pack instead. The shoulder strap pockets were good, a little roomier than my BD. I didn't have any durability issues during the ~12-15 days I've used it. Now that my Kilimanjaro trip is over, I won't use this pack much. Perhaps for a high altitude bivy/climb.
NOT taken on a trip yet. Is well made and designed. I like the flap over top with zipper. The pack is very light but the fabrics seem tougher than other lightweight fabrics.
This will not be a biased review. I love my Fast Kumo Fastpack and wear it exclusively on day hikes unless weather conditions are poor (wet / snowy). I would buy again, and recommend the pack highly. So far, >600 miles with the pack. What I really like? The harness is more like a trail runner vest so it hugs without bouncing around but doesn’t hug too tight. With the right load size, I am never ‘pack sore’ at the end of long 25-30 mile day. The fast belt and pouches work fine as well, and I bought a separate fast belt to replace standard Yar pack belt. Pocket space is ample on shoulder straps as well as side pockets. Back pouch expands to insane size if needed. Interior space is way more than needed. What I wish was different? Not much. First, the size is just 10 l more than I want / need. I could get by happily with a Fast Kumo 26 / 28. Second, I sometimes struggle getting water bottles out of side pockets – I do not use single use plastic bottles so bottle size is a factor. Michael "Goatbells" - https://goatbells.blog
Really like the pack, but the mesh tears easy and the seams through the mesh don’t hold up well
Fantastic! Lite weight, fits perfectly
Perfect for my endurance fast pack training. 100 mile endurance pack race June 7. This pack Carries my 12lb training weight without any problems. Steep elevation changes and even steady paced jogs have not caused any discomfort or issues. Love this thing!
Nice Pack with minor flaws. This is my first fastpack and I have used it over 150 miles and about 7 overnighters. It is a great pack and is perfect for the desert section of the PCT, where I have mostly used it. It also looks great and has a great feature set. My only real complaints are it doesn't fit a small bear vault in it very well, the nylon material doesn't feel that durable, the top lid design isn't great and should be replaced with just a roll top, the zippered pocket on the top lid is fairly useless. Fix these things and I think you have one of the best frameless packs out there.
Super nice pack Super lightweight, tons of pockets and space. The small fit perfectly although if I lose an inch and a half the waist belt probably won't tighten enough to fit. (For reference I'm a 5'3, 125lb male) I also really like the look of this pack. I'm a thru-hiker so I can't attest to the fastpack part but for my purposes it's great.
Excellent product
Wonderful Fastpack I used the bag for two 10-mile winter hiking. It’s great. Lightweight, comfortable, convenient. The front pockets are big and deep enough for phone, water bottle and I also put my thin beanie, gloves, bandanna, sunglasses in the pockets. The pockets at waistband are also good, easier to use than Hipbelt with Pockets for my another GG 65 Silverback. The side pockets are small and tight, not easy to access. It matches the bag better If the fast belt’s belt color is gray. Mines is black. That’s not big deal. In general, I love and satisfy this 36 fastpack.
Excellent Pack for Stage Racing I used this pack for the 250k Atacama Crossing a month ago. For those who may want to know: average distance amounts to a marathon a day with a 44 mile thrown in between. You must carry your food, shelter is provided. This pack worked extremely well and is my choice for next race in April. What worked: size, weight of the pack, design of the harness, fit, various pockets, large water bottle pockets in front that can fit .75L Raidlight water bottles- this is where many American designed packs don’t work. The race requires that you carry 1.5L of water as ever checkpoint and this is one of the few bags that has large front pockets that can do that. What does not work: the pockets in the job belt are small and after months of use I am finding that the zip has a tendency to open up. Also, need an option to attach a front pack. In the end I did not need one and was able to fit 7 days of food in it, but a front pack will increase running efficiency as one would not have to look for race food and drink mix in back on side pockets. Overall, love this pack and would use it again.
Comfy Overall I really like this bag and the way it carries weight. I've loaded it with about 8 lbs so far and it rides nice. The vest pockets hold things well and it's comfortable. For me the only things I noticed that I didn't like right off the bat is the top opening. It's definitely different compared to a roll top. The hip belt pocket is not going to fit if I get any smaller as I have it tightened all the way with minimal layers on. I'm 5'2 115 lbs and I think if I was any smaller this pack wouldn't be as comfortable of a fit. And when I got the pack it seemed to be drenched in febreeze which bothered me for a bit until it wore off as I'm pretty sensitive to chemical scents these days. The pack is pretty cool though and I like how it carries my gear. The purple color would look cool on this pack. Also for me the trash pocket was ineffective, when I carried a water bottle in the pocket the trash would fall out.
Great fastpack! I think the market has limited choices for fast packs and so far I prefer the Kumo What I like - overall GG customer service was great and fast shipping! - comfort! I bought the new outdoor vitals fastpack and took it out on 2 trips. Had hot spots in shoulder and just couldn’t get the fit to be comfortable. I had no problems with the Kumo! Very comfortable! - harness and waist belt storage! Zip for phone, flasks fit great and plenty of storage for quick access - side cord compression! Works great and effective with reducing bounce - all of the features listed are spot on! Smart water bottles were secure and easy to access! What I would love the next version to consider - I’m not 100% sold on the top design and prefer the roll top. - back mesh pocket it’s part of the top lid design but would like to see it deeper by making it straight - bottom mesh. I liked this feature on my OV for quick storage on bittom of pack - phone zipper needs reinforcement to reduce bounce. I love this phone pocket but my iPhone pro had some bounce to it at times - sit pad material. It’s very soft which can be a pro but pack sat flush on lower back and was a bit hot. I like the OV material on the padding. This was more comfortable but breathability was not the best - shoulder straps padding was great but materials are a bit rigid. - I want to fastpack in sierras so a top strap for an empty bear canister like bv425 would be helpful so I don’t have to force it inside.
Run When You Can, Walk Fast When You Can’t, Hike When You Have To… If you like to go fast then this is the pack for you! Even at 19 Pounds there is no sway and no sag while running. If you have a heavy base-weight or do more traditional backpacking then go with the other GG excellent pack options.
Awesome Fastpack I took this pack on a one nighter in the Grayson Highlands with a total pack weight of around 12 pounds. This pack carried extremely comfortably without the hip belt. The chest straps are one of the most comfortable I’ve ever used. I kept water, gloves, and trash in the strap pockets for quick access. The side pockets were difficult for me to grab my water without taking the pack off. This may be user error and may take time to get the technique. I coupled this pack with a Fanny pack which was much more convenient than any hip belt. I’m going to begin incorporating this pack into my daily incline treadmill workouts and I look forward to using it. Excited to take it out west for my future hikes. I would recommend having your gear very dialed in before getting this bag. My previous pack was a Mariposa. I also paired this pack with the gg the One, and I liked being able to put a wet tent into the outer mesh for it to be separated from my dry items.
Great pack, but should be waterproof The Sumo 36 FP is extremely comfortable to wear and well built with tons of utility. Please start making waterproof versions of your excellent packs. Its ridiculous to require dry bags or pack covers for even very moderate rainfall.
Light and functional I got this pack to use on the TMB refuge to refuge trek in September and believe it will serve me well. Took it out over 3 - 10 mile days and it was very comfortable, at times not even noticing I had a 13 pound pack on. It definitely is positioned like a vest and not a hip pac. I like how the side pockets are so far forward, staying out of the way of your arms and making it easier to get at your things. Strap pockets are very functional and easily carry my water bottle phone, sunglasses and snack. My only concern is that I have the waist as tight as it will go and I need it a little snugger ( I'm a size 2). I think I can fold an area over and sew it to make it tighter. Oh - and I wish I had waited 2 weeks when it went on sale!!!!!!
Great Pack -- one little adjustment would be nice This is a very nice pack. I'm not really what you'd call a fast hiker or trail runner. But when I started using a Mariposa 60 I found I really like that style of pack. The Fast Kumo is like a little brother/daughter to the Mariposa. It has the familiar top closing system and similar side pockets. I've used my new Fast Kumo on several short day hikes so far. It carries comfortably and feels great. It has definitely replaced my heavier old daypack with similar overall capacity. Thanks Gossamer Gear for the nice design. The one adjustment I would make to provide an option to add length to the hip belt between the belt's pockets and the pack. This would allow me to have the belt pockets be a little forward instead of back next to the pack. The adjustment could be made by adding two small loops of webbing adding maybe 3-4 inches each and including two more of the small black clips the present pack already has where the hip belt attaches to the pack.
Love it! This was my first Gossamer Gear purchase, but will definitely not be the last! I received it a couple of weeks ago, and have taken it out on the trail once so far, for a day hike. This pack is super comfortable, to the point where I hardly noticed I had anything on. I love all of the storage, and the trash port was especially useful for storing snack wrappers. Water bottle pockets on the strap fit my running bottle just fine. I jogged a bit of the way and didn't experience any bouncing. Looking forward to taking it out on more trips. Definitely recommend.
Fantastic Pack I got my pack maybe one week before my departure from Australia to walk three more Caminos in Spain „Madrid,Sansalvador and the Primitivo „ around 900km I am halfway through my first part the pack is very light I carry around 6.5 kg the setups in the front and back are very practical I have used different Brands before but I think this is by far the most comfortable one I am 70 years old I do about up to 25 km a day and I don’t feel I carry anything an excellent product highly recommend Buen Camino 5 Stars
Well thought out design This is my third GG pack but my first fastpack. I was using my G4-20 for my longer "faster" hikes but wanted something designed for fastpacking to make my time condensed longer hikes more efficient in terms of gear and movement. I like the pocket design and organization in terms of the shoulder strap and belt. I can easily and comfortably store both my 500 ml water bottle, inReach and phone in the shoulder strap pockets then put my "on the move" food in the wait belt pocket. The biggest advantage is being able to run with my full pack weight more easily. The high belt lets me have a natural running movement. The pack secures nicely so that it does not move/bounce around significantly when fully loaded. I've done about 25 miles with the fastpack so far on training runs with a full load pack weight for three days/two night on trail. I've done serval stretches actually running (not walking) of 6 continuous miles on trail and the pack does great. My food, water and base weight combine for two days is 10.5 lbs. the pack easily carries that weight extremely comfortably. I don't think I'll ever exceeding 15lbs total pack weight for a 2 or 3 day trip but I'm looking forward to testing it with a heavier load around that weight.
Nice bottle pockets I just received the pack and have plans to give it a proper test in the next few weeks. I am more of a long hiker than a fast packer, but have been experimenting with fast-pack harness options. What I can say already is that the "fast" model has all the merits of the standard Kumo, which has been a fantastic pack for me. My one small criticism of the standard Kumo was that the shoulder strap pockets were too tight for 700ml bottles. The "fast" version has larger bottle pockets on the straps, so I am thrilled with that. It also has other sundry pockets on the straps, so more quick access options and a balanced load. The higher-riding design and vest-style straps/double sternum strap feel great, but I can't say how worthwhile they are for me until I wear it a few days. Another very clever feature is the openings in the side pockets to allow easier fetching and returning of water bottles. However, I will mostly carry bottles on the straps.
The old Kumo is great, this version looks even better I've put over 1,000 days of hiking on my original camo-Kumo. This pack looks like an improvement for those who want to move quickly. How do I justify this buy to my wife? Hum....
