When it comes to exploring in and around water, the Undercoat™ Water Jacket offers warmth for dogs who can't resist making a splash in the colder, shoulder seasons or who are prone to getting cold when wet. It's an amphibious jacket that thrives in wet environments, using a formfitting laminated neoprene for insulation that stretches and moves with dogs as they romp and swim. Super-soft, articulated stretch StormSleeves™ are engineered to seal in warmth while maintaining freedom of movement.

Can be worn standalone as an insulative piece, or layered under the Float Coat™ Life Jacket if buoyancy is also needed.

    Great for 3-season kayaking.

    The perfect layer under a life jacket to keep my dog warm when wet while kayaking in the spring and fall. He never manages to stay on the boat.

    Great addition to life jacket

    The Undercoat is a great addition to wear under the life jacket. I live in northern Illinois, so this is perfect for early spring and late fall cold water adventures.
