Having a performance mid-layer can make such a difference when you are on the course when the weather takes a turn for the worse. Glenmuir\'s Wick performance mid-layer is a lightweight top that comes with a quarter-zip that is ideal when the weather turns colder. It is made from 90% polyester/10% elastane which allows you an incredible amount of stretch meaning that you are totally unrestricted when swinging the club. This mid-layer gives you extra thermal protection to ensure your temperature is well regulated.
