The Immersion Research Rival Long-Sleeve Men's Paddle Jacket will keep you dry while you're out on the water, courtesy of a three-layer WhiteOut membrane that's bonded to a 70D nylon shell and sealed up with latex cuff gaskets. Immersion Research opted for neoprene at the neck gasket and waistband, which isn't quite as waterproof as latex but is far more comfortable, making the Rival a great option for paddlers looking for a comfortable jacket that can still own serious water all the way until full-on drysuit season. All the Rival's seams are fully taped, and it has a fabric inner tunnel for extra protection and comfort.
