Using the Trekmates Lowick GTX Cap is easy. Just put it on your head like any other hat. The foldable earflaps can be snapped down when it's really cold or folded up when it's not needed. When wearing it, make sure the peak is in front to protect your eyes from the elements. For maintenance, hand - wash it in cold water with mild detergent. Don't use bleach or fabric softeners. After washing, gently squeeze out the water and let it air - dry. Avoid wringing it as it may damage the insulation and the fabric. Store it in a cool, dry place when not in use. Also, check the snap fasteners regularly to ensure they're working properly.
