Taking Measurements 

To determine your torso length, measure the distance between the C7 vertebrae and the top of the hip bone. Write down the measurement- this is your Torso Fit number. Use the sizing charts below to choose a pack that will best fit your body type.

How to Fit Your Pack

 1. Loosen all webbing, straps, and load lifters. Place a moderate load inside the pack. Then, put the pack on by positioning the hip belt over your hip bones. Center the hipbelt along your hip bones, then fasten and tighten it until it is snug.

2. Next, tighten the shoulder straps. Adjust the straps so the pack is held to your back, maintaining the weight of the load on the hips. The shoulder straps should contour around the shoulder. Adjust the load lifter straps to an approximate 45-degree angle.

3. If there is too much space between the shoulders and the back panel of the pack, use our Ergo-Fit™ Shoulder Strap Adjustment System to adjust the pack according to your torso setting. Simply lift the Ergo-Fit strap, raise or lower the shoulder straps according to your needs, then refasten the Ergo-Fit strap to the hook and loop closure on the back panel to secure.
