An arm cover made with specially processed fabric that actually makes you feel cooler when wearing it?! It uses high-quality Japanese-made fabric with a special cooling print applied to the back of a firm, highly stretchy material.When moisture (sweat) touches the dot-pattern printed areas, a xylitol-based resin reacts to create a cooling sensation. The effect becomes even stronger when exposed to wind. We recommend occasionally wetting it, wringing it out firmly, wearing it, and using a handy fan for maximum cooling.The unprinted areas have excellent water absorption and quick-drying properties, so moisture dissipates appropriately.The popular long length covers from the back of the hand to the upper arm — perfect for outdoor activities and driving.UV protection rate: 99.7%Sewing is done in China, so it is labeled as Made in China..
