Outdoor Vitals Carbon Evo 50 vs Outdoor Vitals Skyline 30 Fastpack
Quick take: The Outdoor Vitals Skyline 30 Fastpack costs $92 less; the Outdoor Vitals Carbon Evo 50 carries more (58 vs 26 liters); the Outdoor Vitals Skyline 30 Fastpack is lighter (1.29 vs 1.88 lbs).
Which one to buy
One is a thru-hiking pack and the other is a fastpack, and the $92 gap mostly reflects that. The Carbon Evo 50 carries a stated 40 lbs on two curved carbon stays with load lifters, holds 58 L including about 11 L of external pockets, fits a BearVault 475 and weighs 1.88 lbs. The Skyline 30 Fastpack is frameless with a vest harness and no hipbelt at all, so the whole load rides on the straps. Outdoor Vitals rates it to 20 lbs for base weights of 10 lbs or less.
The Skyline's appeal is speed. It weighs 1.29 lbs, ships with two soft flasks, and its stretch pockets use a UHMWPE blend that resists snagging. It holds 26 L in S/M and 31 L in the large, at one price, sized S, M and L by vest, so check the maker's chart. The Carbon Evo comes in fixed Short (17.7 in) and Regular (19.2 in) lengths with a separately sized hipbelt.
If your trips involve a canister, food for several days or loads above 20 lbs, the Carbon Evo is the only choice here. The Skyline is for runners and fastpackers with a tiny kit who want water on their chest.

Pros & cons
Outdoor Vitals Carbon Evo 50
- ✓A 40 lb rating at 1.88 lb is a strong load-to-weight ratio for a framed roll-top pack.
- ✓Twin curved carbon stays plus true load lifters, a frame layout usually found on heavier packs.
- ✓Mixed Robic and Spectra ripstop body with a 400D Spectra bottom where abrasion is worst.
- ✓The maker names a BearVault 475 as fitting inside, so canister trips are planned for.
- ✓Two zippered hipbelt pockets and a removable hydration sleeve come standard.
- ✓Hipbelt sizes run XS to XL independently of the two torso lengths.
- ✗Only Short and Regular torsos are sold, although the page lists a Tall 21 in spec.
- ✗No adjustable torso, so between-size hikers have to pick one of two fixed lengths.
- ✗Raincover is sold separately.
- ✗The $251.97 member figure is a rebate price; the regular price is $279.97.
- ✗Foam back panel against the body, not a suspended mesh back.
- ✗New in February 2026, so there is little long-term durability record yet.
Outdoor Vitals Skyline 30 Fastpack
- ✓Two soft flasks are included, which most fastpacks sell separately.
- ✓20.6 oz for 26 L total, light for a pack with a foam back panel.
- ✓Challenge UltraStretch pockets use a UHMWPE blend that resists snagging better than plain stretch mesh.
- ✓Internal hydration sleeve and hose port for bladder users.
- ✓One price across all three sizes.
- ✗No hipbelt at all, so the full load rides on the vest straps.
- ✗20 lb ceiling rules it out for anything but a very light kit.
- ✗The large adds 1 oz and 5 L, but S and M share the smaller body.
- ✗No bear-canister room at this volume.
- ✗Robic main body is not waterproof, unlike the laminate fastpacks in this class.
