FootJoy DryJoys Short Sleeve Rainshirt
The DryJoys Sta-Dry Extreme system is a 100% waterproof shell. It's highly breathable, windproof, lightweight, comfortable and quiet. FootJoy warrants that this piece of outerwear will be waterproof in normal use for two years. Waterproof stretch panels allow the garment to move with you, while keeping you totally dry. It's seam-sealed for complete waterproofing. The storm collar is higher in the back and lower near the chin to keep water off your neck and back.
