The Frogg Toggs® Bull Frogg® Rain Jacket features DriPore® technology, which is waterproof and breathable. The Bull Frogg Rain Jacket is constructed from a 100% non-woven "Sig75" polypropylene material made up of three layers, which offers super tough puncture resistance. Frogg Toggs' new and improved seam technology has been incorporated into this design to improve on the durability of this tough suit. The zippers and nickel-plated snaps are designed to eliminate the worry of rust even in a saltwater environment. This material is softer and more durable, resists piling and holds more color, allowing the suit to be offered in a variety of vibrant colors.
