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. Hipbelt sizing: Based on a measurement around the hip iliac crest. Measure around the body at the top edge of the hip iliac crest, approximately 2 inches below the point at which you would measure your waist.
3. Shoulder strap: Sizing refers to bust/chest circumference. Measure around the bust/chest at the fullest point.
