Whether you're running, riding or walking the dog, this UV50+ quarter zip base layer will help regulate your body temperature, with vented underarms to keep you cool and dry. Sweat-wicking 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. Designed to coordinate with the collection of hat silks, saddle pads, fly hoods and other accessories in the most popular LeMieux colours.
