Show Description

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.

  • Made of light, strong silnylon with breathable mesh in areas that touch your body.
  • Seam binding is soft fabric to prevent chafing.
  • Comes with 2, 500mL Ultimate Direction soft body bottles.
  • Water bottle holsters tighten in case you stash a camera or gels inside.
  • Fits a 2L hydration reservoir (not included).
  • Adjustable sternum straps and integrated whistle.
  • Many pockets, including a dedicated phone pocket in front.
  • 2 trekking pole holders you can access on the fly.
  • 2 ice axe loops.
  • Bungee on back panel to keep a windshell handy.
  • Total volume is 11L (7.5L in zippered pockets and 3.5L in unzippered pockets or bottle holders).
  • Measure at bottom ribs. Small fits 61–84cm. Medium fits 79–102cm. Large fits 91–117cm.
