"Absolute game-changer. I put it to the test during my rain-soaked W Trek in Patagonia, and it kept all my gear bone-dry." — Josh W.

This pack is designed for on-trail, off-trail, and all-season environments, with solid-fabric exterior pockets to eliminate snag risk, protect stowed gear, and provide privacy when resupplying in towns.

How to Choose a Pack Size

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.
    • Extra Small (< 15" torso)
    • Small (15.0” - 17.0” torso)
    • Medium (17.0” - 19.0” torso)
    • Large (19.0” - 21.0” torso)
    • Tall (21.0”+ torso)
  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.

Worth the investment

Well worth the investment. The quality in the bag is amazing. The only thing I would change is a removable hip belt and/or I would like to be able to move the hip pockets more forward.
