Our legendary Nasty Pig Union Suit is now available in a custom-plated rib that accentuates every muscle and bulge when stretched over the body. Choose from Dark Cardinal/Black or Army Green/Black. Stretchable comfort and superior fit. Perfect for lounging, sleeping or as an extra layer of warmth.  Although the size selector is normally by waist, height and chest size is a big factor since the waist has plenty of stretch in this garment.  Shorter people would want small, taller people need larger sizes.
