At just 11-1/2 oz. per set, this revolutionary rainwear is the lightest, waterproof, windproof protection you'll ever own. The patented fabric is constructed using three layers of polypropylene with a center layer of microporous film. Outside moisture cannot penetrate, yet moisture vapor generated by your body can easily escape so you'll stay cool, dry and comfortable. The new Pro Angler (jacket/bibs)suits are so packable you can fold them down to fit in even the smallest pack, tackle bag or storage compartment. All seams are fully sealed using a patented process that eliminates needle holes and possible water entry. Machine washable so it keeps its good looks season after season.
