Whether you're enduring nasty hydraulics or a bout of torrential rain, you'll stay bone-dry inside the Immersion Research Double D Drysuit. Breathable fabric and hand-trimmed seam tape makes this suit uniquely comfortable and effective. Sure, you're going to abuse this suit, but Immersion Research saw to that little reality of paddling by providing reinforcements on the butt, knees, feet and elbows. They even tossed in a standard fly zip so you can relieve yourself without de-robing.
