Features

Hydration Sleeve

Pros

  • ✓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.

Cons

  • ✗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.

~$279.97
Ultralight Pack

Released in February 2026, the Carbon Evo 50 is Outdoor Vitals' framed ultralight pack, positioned between the CS40 Ultra and the Shadowlight Carbon 60. Two curved carbon-fibre stays and true load lifters carry a stated 40 lb at 30 oz, and the volume splits into 47 L inside the roll top and about 11 L in external pockets. A bag-only version without the hipbelt sells for $235.

Outdoor Vitals Shadowlight Carbon 60
~$300
