Created for active lives, this LeMieux Ladies Base Layer helps regulate your body temperature, keeping you cool or warm when needed. It features UV50+ protection with moisture-wicking, antimicrobial material and 360-degree stretch. The silky-smooth fabric and ultra-soft flat-lock seams reduce chafing, making it feel like a second skin. It can be worn on its own or layered with gilets or jackets. Additional features include vented underarms for breathability and a quarter zip. Machine washable at 30 degrees.
