Aarn Size Charts

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 looking at the size chart below.

To determine your hip belt size, measure around the hips at the iliac crest (the boney part of your hips), not the waist.

Note that only the hip belts of our bigger packs come in different sizes. Our other packs do come with a one-size-fit-all pelvic form hip belt.

If you are on the cusp, go to the bigger size.

*If you have a larger chest choose the bigger size.
