Gorilla 40 Ultralight Backpack

Back to the old style lid with upgraded features like lighter, tougher fabric and a release buckle for your side compression this is the best Gorilla EVER.

Lightweight but surprisingly durable, the Gorilla is suitable for shorter trips or hikers who know how to crush it in the minimalism department.

The Gorilla holds everything you need when you refuse to bring everything. Winner of Outdoor Gear Lab’s Editor’s Choice award for best mid-volume light backpack, its versatility, durability and comfort make it the best weekend companion you’ll ever have. Also works on longer trips and through hikes with itineraries including grocery/laundry opportunities.
