Gossamer Gear Gorilla 50
The Gorilla 50 is the Mariposa's smaller, symmetric sibling — 50 liters, under 2 lbs, and the classic 'second pack' people buy once their kit shrinks. It keeps the sit-pad back panel and Robic durability in a cleaner silhouette.

Specifications
What do these specs mean? →Features
Pros
- ✓The archetypal 'graduation pack' — the r/Ultralight cliché is buying a Mariposa, shrinking your kit, then buying a Gorilla.
- ✓Under 2 lbs with a real stay and hipbelt, it carries 30 lbs honestly — better than frameless rivals at similar weight.
- ✓Symmetric pockets fix the Mariposa's polarizing layout while keeping generous capacity.
- ✓The removable sit-pad back panel remains one of the smartest dual-use designs in UL.
- ✓Robic fabric durability matches its big sibling's strong track record.
- ✓Mixed torso/hipbelt sizing gives semi-custom fit off the shelf.
- ✓A BV450 fits cleanly; careful packers manage a BV500 vertically.
- ✓Gossamer Gear's service reputation applies here too.
Cons
- ✗50 liters is tight for bear-canister trips or 5+ day food carries — buyers routinely wish for 5 more liters.
- ✗Same sweaty foam back as the Mariposa.
- ✗The 30 lb ceiling is real; water-heavy desert carries overload it.
- ✗Fixed sizes, online-only fitting.
- ✗Mesh pockets remain the wear point in brush.
- ✗The hipbelt is minimal and divides opinion at the top of the load range.
- ✗No lid, no organization beyond the pocket array.
- ✗Price sits close enough to the Circuit that many first-time buyers default to ULA's bigger volume instead.
