Choosing the Right Pack:

Torso Sizing:

Torso Size Info

All packs are built to your specific torso. 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. 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.
