Daiwa Danrotech Mid-Neck Undershirt DU-3623S Men's Black Fishing

These underwear absorb and reflect far-infrared rays emitted by the body, keeping you at a comfortable temperature even when the temperature changes between day and night. Danrotech Undershirt with Water-Repellent Cuffs Made with a soft, fluffy, and warm fabric that envelops you, it's designed to maintain a comfortable environment inside the garment at all times. The lining is woven with hydrophobic (water-retaining) polypropylene material to prevent sweat from cooling you down, reducing the drop in body temperature caused by sweat in winter. The cuffs are made with water-repellent ribbed material, which is designed to prevent water and seawater from absorbing through the cuffs.
