Getting a new pack is EXCITING! Especially if you are getting an Aarn Pack & Pockets.

To help choose your pack, first you need your back length by measuring your torso. Then you will need your hip-belt measurement. Don't worry - we have easy instructions below.

After that, choose your volume and adventure!

how to measure your torso for a back pack

What is your torso length?

You will need:

A soft measuring tape and a friend.

1. Tilt your head forward and feel for the bony bump where the slope of your shoulders meets your neck. This is your 7th cervical (or C7) vertebra—and the top of your torso length.

2. Next, find your Iliac Center. This is the point in the centre of your spine that aligns with the highest boney point on your hipbone.

3. Tilt your head back up and have your friend run the tape straight down your spine from your C7 until you reach your Iliac Center

This is your torso length. Check it twice to be sure! Use your torso length to determine your pack size.
