Sunice\'s Half-Zip Hybrid jacket is the perfect mix of a warm, thermal jacket and a stretch pullover mid-layer. It has a quilted Climaloft front which helps to trap your body warmth between the fabric to keep you warm on the course for longer. The breathability is fantastic and will keep you warm without letting you overheat and become too hot if the weather takes a gentle turn. The sleeves and back area have stretch fabric which allows you to keep a good range of motion whilst still keeping warm.
