The durable 2-ply Supplexr shell makes this a must for all occasions - totally windproof and water resistant. Soft durable Supplex nylon gives it a cottony soft feel, while the full cut gives you unrestricted movement. Ribbed knit cuffs, collar and waistband keep the elements out. Double needle sewing will stand up to rugged activities. It has a stylish crossover knit collar. It's perfect for layering over one of our golf shirts, or under one of our Polartec pullovers.
