Getting Your Size
The key to a confortable pack load is the properly fitting backpack. We've designed a more custom fit into our packs with simple sizing based off two measurements. To find the appropriate size waist and yoke for your pack, collect the following two measurements, then reference the sizing chart below.

1
Waist Circumference
Measure around your waist just above the top of your hip bones (roughly two fingers below your belly button).
2
Torso
Use a tailors tape measure or string and have a friend measure between the bony bump at the base of your neck (C7 vertebra) to the spot on your spine that is just behind your belly button.

In Between Sizes?
If you are between sizes on the waist belt, we recommend you size down. If you are between sizes on the yoke or if your measurements fall outside standard sizing, please contact Customer Service at 1.833.548.1999. Purchasing packs outside of standard sizing is possible through our Custom Sizing Program. There is typically an additional cost associated with this purchase.
