Our sizing guide is calculated to give riders a general idea on what brace size they should wear based on the size of their waist measurements. Simply select the size according to your waist measurement. For each and every size, you are given a minimum of 4" overlap of the waist straps to ensure proper fitting and maximum effectiveness.
If your measurement are between 2 sizes, chose the one which is closest to your measurement. Otherwise, either one works just fine for you.
Note: The height of the back brace is fixed at 15.35 inches (39 cm).
