With an attached drawstring hood, a double storm flap with non-corrosive snaps, and double welded seams for extra durablility, the weather elements dont stand a chance. So keep the warmth in and seal out the cold by layering with our calcutta t-shirts, long sleeves, sweatshirts and topping it off with a nice heavy duty rainjacket. .
