Most leg warmers are Roubaix-fleece tubes. The better ones have articulated knees. CapoForma does the competition one better with their CSS Legwarmer. The leg warmers have an upper panel, a lower panel, an articulated knee, flat-lock seams, and a silicone gel gripper to hold everything securely. Not only that, these warmers use Windtex Topazio fabric -- it's a stretchy Windtex -- to keep the windward portions of the leg warm. And there's Super Roubaix fleece for comfort, warmth and breathability where the wind doesn't hit. The color is Black. Sizes are S/M and L/XL.
