The ProFlex® 1650 Back Support is designed with an adjustable two-stage closure. Pull the first stage closed for an exact fit, then when ready to lift, pull the second stage tight for the desired tension. Single-layer, 8"-wide elastic cinch strap offers positive tension. The 1-1/2"-wide knit elastic suspenders are adjustable and cut wider to improve comfort and fit. The back support can hang loosely by the suspenders when not needed, and if the user prefers to wear the support without suspenders, they are detachable. The knit elastic body material is durable and comfortable, providing firm support and excellent fit. Machine washable.
