Nike Dri-FIT Club Structured Heathered Cap This mid-depth Club Cap offers the best of both worlds: it's made from lightweight, sweat-wicking twill, and yet it's also structured to keep its shape all day. Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. Nike AeroBill technology combines breathability with sweat-wicking comfort to help reduce distractions. Made with lightweight, woven twill for a classic ball cap feel. Tri-glide closure lets you lock in the perfect fit.
