It breathes when I breathe
This under layer is the best I have ever worn. It keeps me warm, dry, and comfortable all day. Sitting on the lifts it holds my heat in so that I don't get cold, and when you start moving it breathing and wicking your sweat keeping you dry so you don't get cold when you stop. Not to mention it doesn't smell after a long day of shred, and gets you the ladies at the after party with it's good looking pattern.
