It’s made of double-layered PowerSlim our trademark firm compression fabric to sculpt the chest, abs, and back. This shaper has a 3-level adjustable front hook-and-eye closure with a protective inner lining to prevent metal-on-skin contact. This tank features 4-level hook-and-eye adjustable straps for extra support. Criss-cross posture corrector bands provide back support, even for days where you have to spend a long time in a seated position. This innovative shaper vest can be worn for post-surgical recovery in addition to daily wear and activewear.
