Our bestseller. With a removable internal frame, load lifters, and 7 built-in pockets, this is a gear-hauling workhorse that weighs in just 2 pounds.
This award-winning pack’s roomy main pocket holds your shelter, clothing, sleeping pad and food.

Made of custom 100 and 200 denier Robic nylon fabric, this tough, light pack delivers a very comfortable carry even with a overloaded 35 pounds of gear.

Will a Bear Canister fit inside a Mariposa? Yes, all models of bear canisters will fit vertically in this pack! Smaller designs like the Bare Boxer and the Bear Vault 450 will fit horizontally in the main compartment.
How do I attach trekking poles or an ice axe to the backpack? We suggest using our Pole Storage Bungee and then running that through one of the many attachment loops provided on the packs exterior. This will insure secure storage.
