A past Editors' Choice winner, the Gossamer Gear Gorilla is an excellent ultralight backpack. It's sibling, the Gossamer Gear Mariposa, took over the highest honor in our latest review, but we're still big fans of the Gorilla. It's not the most lightweight model tested, but it handles light to medium loads (up to 30 lbs) with ease and comfort. When casting off in winter with five days of food and fuel, the durable "simple frame" enabled the well-padded shoulder straps and waist belt to distribute the weight comfortably. When carrying smaller loads, the Gorilla still holds its own and carries very well. Furthermore, the removable egg crate contoured "SitLight" foam back panel offers top-notch ventilation. Basically, we love how this pack carries! The feature set on this pack is stacked, too. With large external pockets on the back and a large lid for stowing smaller items, there is plenty of storage space inside and out on this pack.
Gossamer Gear informed us of some modifications to the lid design of the Gorilla that were implemented in the final days of 2017. The latest version is pictured above. More details on the update are found below.
