Undercoat™ Dog Water Jacket

water-friendly insulation

Color

Selected: Campfire Orange

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.

STRETCH SLEEVES

    Quality

    Bought a medium for my 4 month old Labrador puppy and it fits nicely with a plenty of room for her to grow into it … it’s a Christmas gift so she only got to try it on before I wrapped it!

    Very nice quality and love the covered zipper and the way it unzips along the entire length of the shirt! Very easy to put on and take off!
