This lightweight, innovative cap uses three-layer Aquasealz technology, keeping you 100% dry without sacrificing breathability. Designed to slide comfortably under your helmet, it's the perfect fit for any cycling adventure, rain or shine. Say goodbye to soggy rides and hello to premium comfort! The Trunch is fully waterproof, making cycling in the rain a breeze. Features a durable polyester and nylon blend outer, a waterproof and breathable Aquasealz membrane, and a polyester lining to wick moisture. The raised peak improves visibility in wet conditions, preventing water from running into your eyes. Its close-fitting silhouette sits perfectly under a helmet, and excellent breathability makes it suitable for warmer climates. An internal Coolmax® sweatband prevents perspiration from dripping down your brow. Easy care: wash at 30ºC, drip dry, and avoid dry cleaning, ironing, or bleaching.
