The Signature Bull Frogg Jacket features waterproof and breathable DriPore technology. The Bull Frogg is constructed of three layers of a 100% nonwoven, super-tough 75 gram polypropylene material to offer outstanding puncture resistance. The jacket incorporates a new raglan sleeve and shoulder design, as well as improved seam technology, that allow for a better and more comfortable fit, as well as higher durability. The molded polymer zippers and nickel-plated snaps eliminate the worry of rust, even in a saltwater environment.
