Do it all in this UV50+ quarter zip base layer. Its technical fabric regulates your body temperature, with vented underarms to keep you cool and dry. Contrast matte logo print is a subtle sign of the quality you expect from LeMieux. Sweat-wicking, anti-microbial and with 360° stretch for unrestricted comfort, there's nothing this base layer can't do. The silky-smooth fabric, ultra-soft seams and flat lock stitches reduce chafing and keep bulk to a minimum when worn under a fleece, jacket or gilet.
