Created for active lives, this LeMieux Base Layer helps regulate your body temperature, keeping you cool or warm as needed. It offers UV50+ protection with moisture-wicking, antimicrobial material that also features 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. Features include UV50+ protection, temperature regulation, moisture-wicking properties, and vented underarms for breathability. The antimicrobial material and 360-degree stretch ensure comfort and freedom of movement. Ultra-soft flat-lock seams minimize chafing and bulk when worn under other layers. The base layer is also equipped with a quarter zip and is machine washable at 30 degrees.
