Outdoor Vitals Skyline 30 Fastpack vs Gossamer Gear Fast Kumo 36
Quick take: The Outdoor Vitals Skyline 30 Fastpack costs $2.03 less; the Gossamer Gear Fast Kumo 36 carries more (36 vs 26 liters); the Outdoor Vitals Skyline 30 Fastpack is lighter (1.29 vs 1.3 lbs).
Which one to buy
Both are frameless fastpacks with vest harnesses, at about the same price and the same 1.3 lbs. The Fast Kumo 36 is the more capable of the two. It holds 36 L against the Skyline 30's 26 L (31 L in the large), and it adds a detachable Fastbelt with zip stretch-mesh pockets, where the Skyline has no hipbelt at all and puts every pound on the straps. Gossamer Gear rates the Kumo to 25 lbs with comfort topping out around 20; Outdoor Vitals rates the Skyline to 20 lbs for base weights of 10 lbs or less.
The Kumo's S/M (14-20 in) and M/L (16-23 in) torso ranges overlap, so sizing it from home is straightforward. The Skyline comes in S, M and L vest sizes.
The Skyline's advantages are in the box: two soft flasks, an internal hydration sleeve with a hose port, and snag-resistant UHMWPE-blend stretch pockets. The Kumo has no hydration sleeve, and its warranty is one year for US buyers. For most fastpackers the Kumo's extra room, belt and overlapping sizes win; the Skyline's case rests on the flasks and bladder sleeve in the box.

For runners and fastpackers who want soft flasks included and a hydration sleeve, with a very light kit.
Gossamer Gear Fast Kumo 36
Made for fastpackers who want more volume, a detachable belt with pockets to take weight off the shoulders, and overlapping torso sizes.
