Torso Sizing:

Hip Belt Size

PLEASE MEASURE YOUR WAIST! Just because you wear a 32 pants size doesn't mean you have a 32" waist. Below you will find our hip belt specifications. The first measurement below (the absolute minimum) is the total length of foam and clip. The second measurement is the maximum the straps will extend to. Using a measuring device, pull it around your back at the level of your iliac crest and connect it in front of you. This will be the hip belt size that you select from the drop down menu. Using this pack for a thru-hike? Please take weight loss into consideration when selecting your hip belt size.

Small Hip Belt - 25" of foam and a total of 38" of adjustability.

Medium Hip Belt - 28" of foam and a total of 44" of adjustability

Large Hip Belt - 33" of foam and a total of 48 " of adjustability

X Large Hip Belt - 40" of foam and a total of 55" of adjustability

Torso Size Info

All packs are built to your specific torso, SO PLEASE MEASURE CORRECTLY!!! To find your torso length you will need to find your C7 vertebrae and your iliac crest/hip shelf and measure the distance between them. If you fall in the meddle of two sizes we recommend sizing down. Still need help finding your torso? Check out this video

Packs without a hip belt will measure from the bottom of the pack to where the shoulder straps are sewn in. This is the same for packs with a 1″ removable hip belt or fanny pack.

Packs with a padded hip belt will measure from the center of the hip belt to where the straps are sewn in. If you choose to have load lifters then your pack will measure from center of hip belt to the load lifters.
