This lightweight polyester white cap keeps out the sun’s rays in the summer, and the chill in the spring and fall. The 6-panel design fits the head well and the Velcro adjustable strap ensures the cap stays in place, whatever your speed. Ventilated panels ensure heat is dissipated and the polyester fabrics and peak are machine washable. An essential piece of kit for a runner’s wardrobe, especially for one who is born bound.
