Designed in collaboration with ski legend Cody Townsend, the Crux 40 litre pack is the ultimate pack for skiing, climbing, and the safe transition between the two. Built with practicality in mind, the Crux features a YKK zippered back panel entry for quick and easy access on the steepest of slopes or cliffs.
The removable hip belt is constructed with Hardline Dyneema and dual-density closed-cell rigid foam for added comfort and has a gear loop and ice clipper slot on the right side and a single zippered pocket on the left. Need more storage space? The double drawstring closure provides for an additional 15 litres of storage when fully extended.
Your torso length, not your height, determines your pack size. We recommend the following to determine yours:
1. Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
2. Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
3. Place your hands on your hips so you can feel your iliac crest, which serves as the “shelf” of your pelvic girdle. (It’s the first hard thing you feel when you run your fingers down from the sides of your ribcage.) Position your hands so your thumbs are reaching behind you.
4. Have your friend finish measuring at the point where the tape crosses an imaginary line drawn between your thumbs. This distance is your torso length.
5. If your measurement falls right in between sizes (for example, if you have a 17.0” torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.

| Size | Torso |
|---|---|
| Extra Small | < 15" |
| Small | 15.0” - 17.0” |
| Medium | 17.0” - 19.0” |
| Large | 19.0” - 21.0” |
| Tall | 21.0”+ |
