This warp knitted skull cap is so stretchy, so versatile, and so soft you will never want to take it off. The revolutionary warp knit technique, like that used in the GripGrab Freedom Base Layers, creates a second skin feel. It also greatly enhances the usability of the product; thanks to its lightweight and slim profile, it can be used under a helmet, as a running skull cap, or worn casually off the bike.
