The Omius cap combines modern design with innovative cooling technology. Specifically developed to support the body's own cooling, it provides comfort in high temperatures – whether during sports or on the go. The cap is lightweight, ergonomically shaped and features a silicone grid that holds the 20 separately sold cooling pieces directly on the skin. These stones made of porous graphite with a hydrophilic coating increase evaporation, creating an immediately noticeable, long-lasting cooling effect. The large size (~58 cm) offers an optimal fit for most head sizes without pressure, and the low weight of only 55 g makes wearing comfortable even during extended activities.
