Pros & cons
Gregory Focal 58
- ✓Beats the Exos at its own game in most head-to-heads: similar weight, real hipbelt pockets, and a pivoting belt the Osprey lacks.
- ✓The FreeFloat suspended mesh breathes as well as anything under 3 lbs.
- ✓The dynamic hipbelt pivots with your stride, which reviewers credit for less hip chafe on long days.
- ✓Dual zippered hipbelt pockets fit large phones — called out approvingly in nearly every review.
- ✓The fixed lid-less design with a big top pocket keeps the silhouette clean without lid flop.
- ✓At 2.57 lbs it undercuts the Exos while including more standard features.
- ✓Gregory's lifetime warranty matches Osprey's on paper.
- ✓The 100D body with 210D reinforcement has held up well in long-term reviews.
- ✗Fixed torso sizes (no adjustability) is the biggest spec gap versus the current Exos.
- ✗The suspended mesh bows into the bag and complicates bear-canister packing, same as every trampoline design.
- ✗Availability is far thinner than Osprey's — few stores stock it to try on.
- ✗The 35 lb rating is optimistic per heavier users; 30 lbs is the practical comfort line.
- ✗The stretch front pocket is smaller than the Exos's and fills fast with wet gear.
- ✗No removable lid means no weight-stripping flexibility.
- ✗Bottle pockets require a shoulder-dislocating reach for some torsos.
- ✗Brand recognition lags in the UL scene, so resale is softer than Osprey or cottage brands.
Gossamer Gear Gorilla 50
- ✓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.
- ✗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.
