A long sleeved base layer providing excellent warmth. Because you need a variety of under layers, I rotate this into my first layers. Made of a moisture wicking polyester fabric, it contours to your body. Stretch fabric increases mobility. Flat sewn seams add comfort and diminish the chance of a seam creating hot spots. Antimicrobial treatment eliminates odors. Color choices include black, blue, and pink. I really like the zipper neck, which adds the possibility of ventilation in warmer conditions or when you are hanging in the base lodge. It is well worth the money.
