A mountain-running design created for ultra-runner Anton Krupicka, an athlete who knows about efficiency and elevation. It’s super lightweight but still has lots of room for spare layers, fuel and trekking poles. Your water rides up front for hydrating on the move, and the bounce-free design doesn’t interfere with your stride, even on steep descents.
