Hipbelt Sizing: (Please let us know what size hipbelt you want in your purchase notes)

  • Men use the waist of your pants and add 2”. For example, the waist of your pants is a 32, add 2 to get to 34. If you are on the edge of a size, go up.
  • Women measure the smallest part of your waist, and add 5”. For example, your waist is 28, add 5 to get 33.

Choosing A Shoulder Strap Style:

J straps are traditional and work best on men and women with average builds. If you are very large in the upper body you might need XL shoulder straps. Men with athletic builds who have strong square shoulders will find the S straps work better. If you are a climber, weight lifter, triathlete or similar, consider purchasing the S strap.

Measuring Your Torso

Length: Torso measurement is the best guide for proper pack fit. If you are between sizes on the torso choose the smaller size. Conversely, if you are between sizes on the hip belt, choose the larger size. Follow these steps to accurately measure your torso. Stand upright and tilt your chin to your chest. Locate the largest lump on the back of your neck located close to the base of your neck. Make sure your pants or short are sitting just above the top of your hipbone. From the large bone at your neck, measure the length and natural curvature of your spine to the top of your waistband. This is your torso length
