Sizing and Fitting of your Osprey Pack

Fit is the key to pack performance. Take the time to get it right. Most Osprey packs are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the picture below) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).
Use the table below to determine your pack size.
