Gossamer Gear Fast Kumo 36 Fastpack

The Gossamer Gear Fast Kumo 36 is a frameless fastpack with 36 L total capacity (28 L main compartment) and a weight of 610 g, built for trail running and fast, stripped-down multi-day travel (ultralight thru-hiking). The vest-like fit hugs the body closer than a conventional back system, so the pack moves less while running or moving fast. A detachable padded hip belt with pockets keeps small items within easy reach without taking the pack off, and two side pockets cover bottles or soft flasks. The 70D Robic Nylon body is more durable than the thinnest ultralight fabrics, while the absence of load lifters reflects a focus on lighter loads rather than heavy multi-day carries. Access to the main compartment is via a top lid, and there's no integrated rain cover. It suits users combining running and hiking on ultralight trips who prefer a smaller volume, with a volume-to-weight ratio around 59 L/kg.
