*Note: These height recommendations are for an average body type. If you have longer legs and a short torso then you may need a shorter frame. If you have shorter legs and a longer torso then you may need a taller frame. When in doubt choose a taller frame. The load lifter angle from the shoulder strap to the bag or frame should fall between 35 and 45 degrees with the pack moderately loaded.
If your measurements are in between those listed in the size chart, pick the next larger size.
