This UV50+ quarter zip base layer harnesses a versatile smooth, sweat-wicking fabric to keep you cool and dry when the heat is on, yet provides a warm base layer when you need it.

360 degree stretch ensures long-lasting unrestrictive comfort in the saddle. There are underarm vents for breathability, while ultra-soft seams with flat lock stitches eliminate bulk when worn under hoodies, jackets and fleeces.
