Shirt Jacket made in a light nylon rep with an ultra-tight weaving construction. The resin coating of its inner face makes it wind-resistant and mildly water-resistant. Due to the resin treating of the material, the color penetrates unevenly into the material, lending a crinkle aspect to the surface. The garment is padded with a substrate of Polartec® Alpha®, a gauzed run-proof polyester substrate first conceived for military use that is ultra-breathable and extremely reactive to changing temperatures. Garment dyed with the addition of a special PFC-free anti-drop agent.
