This high performance garment has been constructed with a stretch fabric to give you greater mobility when you play golf. Plus a moisture transport system that removes any access moisture away from the body to keep you dry and comfortable. For added performance the layer has anti-odour technology which offers less distraction, and prevents the build up of odour causing microbes. Finer details include a 1/4 zip opening and has a raised neck to help lock in your natural body warmth.
