It features UV50+ protection, moisture-wicking antimicrobial material, and 360-degree stretch for ultimate comfort. The silky-smooth fabric and ultra-soft flat-lock seams reduce chafing, making it feel like a second skin. This versatile base layer can be worn on its own or layered with gilets or jackets. It is also machine washable at 30 degrees.
