ALL THAT GLISTENS - Low rise fit - Flat lock seams - Heat sealed branding to upper hip and back of waistband - Main: 78% Polyester, 22% Elastane. Secondary: 91% Nylon, 9% Elastane. With leggings, it’s as much about fit as it is about function. The Illumination Leggings have nailed both. A classic low rise fit with a pocket to the hip and flat lock seams to ensure comfort. Plus, an ankle stirrup you can hook over your foot to make sure they stay put, even when you're speeding in spin.
