Dry-Plus® is a waterproof, breathable, windproof membrane that can be bonded to fabrics to provide a supple, quiet barrier against precipitation and other forms of moisture. Though it keeps moisture out, Dry-Plus® also breathes to allow perspiration to escape, preventing wetness build-up in underlayer garments. Take our word on it, Dry-Plus® will keep you dry and comfortable-inside and out. Try any Cabela's Dry-Plus® garment risk-free for 60 days. If you are not satisfied for any reason, return it for a full refund.
