The AX45 is based on the previous (no roll-top) Crux AK47 but made of Cordura/Dyneema rather than Kevlar fabric. A very well designed lightweight but tough 45 litre winter climbing/alpine sack.

Instead of the AK's famous Kevlar fabric, the AX45 has a lighter Cordura fabric with a 3 mm Dyneema ripstop developed exclusively to Crux's specification. Other changes include changing the frame to twin tubular stays and using narrower webbing (webbing adds a surprising amount of weight to a rucksack). Although the carrying harness is identical to that of the AK sacks, the AX45 has a new feature – the hip belt can be fully removed, leaving just the webbing to fasten around your waist.
The AX45 comes in a two back lengths – Regular (for those up to around 5’11” or 180cm) and Long.
  • External lid pocket.
  • Security pocket on inside of lid.
  • Does NOT have an extending lid.
  • Side compression straps – quick and easy to fit or remove.
  • Oversized back haul loop – easy to grab and clip.
  • Top compression strap.
  • Dual drawcord closure system on extension sleeve.
  • 3 mm Tendon drawcord – Crux suggest that it can be used as an emergency abseil sling (but beware it is only 1.4kN and could cut easily on a sharp edge).
  • 40mm webbing waist belt with removable hip belt.
  • Internal sleeve for hydration bladder.
  • Two ice-axe holders for modern axes.
  • Wand pockets.
  • Reinforced, double-layer base panel.
Fabric: 15% Dyneema / 85 % Cordura, 150 g/m².
Frame: Two 7mm tubular titanium stays (removable).
Capacity 45 litres.
Weight:  ca 1150g.
