The Vapor Base Layer series offers the technical properties of a synthetic fabric with a more natural, comfortable feel.

The Vapor Base Layer Half Zip is made from a brushed poly jersey from Italian fabric mill Lanificio Becagli. It's naturally wicking and provides excellent moisture control during heavy aerobic activity. The fabric is slightly elastic, which allows for easy movement and a greater range of motion.

The Vapor Base Layer Half Zip features an extra-tall zippered neck to lock in warmth on those particularly cold days. It comes with thumbholes at the cuffs, which can be used to create a seamless connection underneath a pair of gloves or bypassed for a more relaxed fit. An extended bottom panel has been added in the back to make it easier to tuck in and to prevent it from riding up during movement. The entire garment has also been constructed with flatlock seams to help prevent chaffing along the seam lines.
