Undercoat™ Dog Water Jacket

water-friendly insulation

Color

Selected: Aurora Teal

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.

WATER-FRIENDLY WARMTH

Laminated neoprene body is flexible and provides insulation in wet environments.

STRETCH SLEEVES

    Better than Hunting Vest

    I got this for my German Shorthaired Pointer (Rio) for rafting the cold rivers we run in Colorado. He usually wears a neoprene hunting style vest under his PFD that just covers his core. I like that this jacket has a little more coverage over his rump and arms for a little extra warmth and the color helps him be more visible as he romps the banks. I paired it with a Confluence life jacket from Ruffwear and love the combo. Still haven't floated with it yet, but the fit accommodates his large chest well and the build seems high quality like everything else we've ever ordered from Ruffwear.

    Helps my chilly collie!

    My border collie has more energy than sense and loves to swim all year round. This jacket keeps him from shaking a little longer when the water temps are down! I I think his new little sister is going to need one now, too.

    Excited to try

    After measuring before ordering, this fit my pup great! He's still growing, and he should have room to grow a bit more. I'm hoping this will help him stay warm in cold water adventures this winter, as he tends to be a bit of a chilly guy!

    The Ruffwear Undercoat Dog Water Jacket is pure genius.

    It’s sleek enough to double as my raincoat and to wear under my water Confluence life jacket—so whether I’m wading through streams or strutting through puddles, I stay warm, dry, and fabulous. The fit hugs my noodle body without feeling bulky, which is critical because, let’s be honest, I have zero insulation of my own. It’s flexible enough for full zoomie range, and it layers perfectly under my Confluence Life Jacket when I’m really going for the aquatic fashion award. Rainy days used to be tragic. Now they’re my runway.

    Signed with soggy pawprints, Naia Moon the Whippet— unofficial puddle princess, and the most spoiled (and stylish) pup on the block. I am 28 lbs with a long skinny body and wear a size small. It fits pawfect!
