Caps made of lightweight and functional C9
Swedish-born outdoor wear brand Houdini Houdini's clothing is immediately adaptable to activities such as climbing, skiing, trail running, and biking, and combines functionality and simple design that can blend in with any situation. The company's pursuit of comfort in their products is very similar to CIRCLE's approach, even if the products are different.
The C9 Cap is an ultra-lightweight, functional cap for high pulse activities and water sports. Made of C9 Ripstopâ„¢ fabric, which is quick-drying, breathable, both wind and water resistant, it is so lightweight you'll forget you're even wearing it. It is also durable for years of comfortable use and protects your head from the harsh direct summer sun whether you are running, trekking, kayaking, or playing beach ball. The back of the head has a drawcord for adjusting the fit.
