Important! Do not select the frame size based upon the pack volume.
Packs are sized in Regular (R) and Tall (T). Sizing refers to your back length.
To determine your size, measure down the spinal column from the 7th cervical vertebra to the level of the hip iliac crest.
Hip belt sizing is based on a measurement around the hip iliac crest. Measure around the body at the top edge of the hip iliac crest, approximately 2" below the point at which you would measure your waist.
Shoulder strap sizing refers to bust/chest circumference. Measure around the bust/chest at the fullest point.
