The mouth/nose cover and crown panel are made with perforated neoprene to allow ventilation. As the material warms to your body temperature, it will expand to allow additional flexibility.
Neopren Care Instructions:
To ensure as much fun as possible with our neopren-products, we recommend you follow the care and storage instructions. Cleaning: Combine lukewarm water with some mild soap and swirl over the product while gently pressing. Avoid excessive rubbing. Alternatively: Wear your neoprene under the shower and wash it down while on the body. In both cases you have to rinse it carefully with clear water. Lay it flat somewhere airy and let it dry. Storage: Keep away from sun light and heat sources and store it with enough hanging space. Do not store it folded or squeezed. Most appropriate are shaped hangers or trouser hangers.
