Gregory Fit Guide

If there’s one thing we could leave you with, it’s this: Don’t size your pack like your t-shirt, size it like your shoes. But since we own a whole page here on the Internet and have decided to dedicate it all to making sure your pack fits well and comfortably, we don’t have to leave you with just that.

Fit and sizing for your backpack is important for a whole bundle of reasons. Having a well-fitted pack allows you to stay comfortable and use less energy on the trail—which is good for you. It also allows you to use your pack correctly and to fill it to its maximum capacity for optimal performance—which is also good for you.

Step 1: Measure Your Torso Length

C7 Vertebra to Iliac Center

Grab a measuring tape. Tilt your head forward to make it easier to and find the highest protruding knob at the base of your neck. Ahoy! It’s your C7 vertebrae—the starting point for your soft measuring tape. Tilt your head back up and run the tape straight down your spine until you reach your Iliac Center. This is the point in the center of your spine that aligns with the highest point on your hipbone.

Having a well-fitted pack allows you to stay comfortable and use less energy on the trail—which is good for you. It also allows you to use your pack correctly and to fill it to its maximum capacity for optimal performance—which is also good for you.
