Ultralight performance cap made for high pulse activities and watersports. Perfect for running, training, hiking, kayaking or any other summer outdoor sports. The design team at Houdini felt that they were missing a product for those activities when a regular baseball cap would be too heavy or clunky. They found the perfect performance fabric and the C9 Cap was born. The C9 cap will keep your head dry, cool and shaded but you wont even know you are wearing it. C9 Cap is made from C9 Ripstop, an ultra light, cool and highly breathable fabric. Its made from 100% recycled and recyclable polyester, eliminating the concept of waste. Its treated with a biobased durable water repellent free from any PFAS or other toxic chemicals. Despite the light fabric, this cap is both wind- and water resistant. It dries very quickly and will shade your head from direct sunlight. Slim fit Ultralight Quick drying Adjustable in back Excellent air permeability Soft next-to-skin comfort Dull and silent surf
