Ultralight materials and breathable back panels manage sweat when you're working hard over long distances. Capacities typically range from 5 to 15 litres, enough for hydration, nutrition, a spare layer, and a mandatory kit for mountain races or fastpacking trips. Adjustable chest straps and elastic pockets keep everything locked down, even when you're bouncing across rocky ground.
These packs shine on fell runs, ultra races, fastpacking missions, and any mountain day where you're covering big distances quickly. Trail runners switching from standard rucksacks notice the difference immediately: less movement, better access, and gear that actually keeps up with how fast you're moving. Browse our range of active packs and find the right vest for your next fast mountain day.
