Measurements for the shoulder strap and hipbelt components of the Aerios packs can be found below.
How to find your measurements:

Note: Calculate your own body measurements, then select your product size.
1. Back Length: To determine your size, measure down the spinal column from the 7th cervical vertebra and the level of the hip iliac crest
2. Shoulder strap: Sizing refers to bust/chest circumference. Measure around the bust/chest at the fullest point.
3. Hipbelt: Sizing is based on a measurement around the hip iliac crest. Measure around the front of the body at the top edge of the hip iliac crest, approximately 2 inches below the point at which you would measure your waist.
Interchangeable shoulder strap and hipbelt components
It is possible to interchange different size shoulder strap and hipbelt components on many Arc'teryx Packs, but this will not change or affect the back-length of the pack. Aerios packs are shipped with medium hipbelts and shoulder straps.
Please contact the retailer where you purchased your Aerios Pack or Arc’teryx Customer Service if you require a different size. Please note, the hipbelt & shoulder straps must be in new condition to facilitate an exchange. Additional charges will occur if the belt or strap has been previously used.
