“The comfort and versatility of this LS base layer are so dialed in I need to buy a second one ‚Äî right now. It stretches but never feels tight. It breathes without getting sopping wet. Above all, it keeps me warm enough under a jersey, shirt, or jacket that I'm wishing for (not worried about) cold weather. This piece is so essential to winter riding that I only notice it when I'm not wearing it. Thus, the clear need to purchase a second one. I love it!”
