How to Measure

Torso:

Ask a friend to run a tape measure from the top of your shoulders (i.e the same place where the collar on a crew neck T shirt finishes), down your back to your waistline (ie the small of your back, at the same height as your naval or the top of your hip bone).

Waist:

Run a soft tape measure around the narrowest part of your waist, just above your hip bone and in line with your naval.

Torso Length

In Our Opinion

The Patagonia chart is accurate and reliable and your backpack will fit if you refer to the measurements given. We are confident in the fit of Patagonia backpacks because:

● They have gone to the trouble of preparing this size information!

● We have tried them ourselves, in a full range of models and sizes.

● We see customers testing for size in our Mountain Sports Shop

● We have been selling them for years!
