Product Description
Warmth without the bulk, freedom without compromise
The EzyDog Thermax is a thermal dog winter vest designed to fit under a harness. Imagine your dog staying warm on cold winter walks while still wearing their harness comfortably. The Thermax delivers cosy insulation in a slim-fit design that works seamlessly with your existing gear, so your dog gets the warmth they need without sacrificing mobility or control.
Available in Orange and Black in sizes XS to XL, the Thermax suits all breeds from deep-chested Vizslas and slender Greyhounds to Labradors and Spaniels.
Why the Thermax Vest is the perfect layering solution
Its ultra-slim, 4-way stretch fit makes it the perfect base layer to wear underneath a harness. The ergonomic zip-up design contours to the body, ensuring no cold air gaps and zero snagging on undergrowth. For slim-breed dogs like Greyhounds, Whippets and Vizslas, the ergonomic fit is especially effective, as there is no bunching under the harness and no restriction to the natural gait.
How It Helps:
- Under-Harness Compatibility: The slim profile allows you to put your favourite harness over the vest with no bulk.
- Body-Heat Insulation: Lattice polar fleece lining reflects heat back to the core for extreme warmth.
- 4-Way Microfibre Stretch: Total range of motion - ideal for running, hiking, and agility.
- Thermoseal Taped Seams: Fully water-resistant with a YKK back-zip to keep the spine dry.
-
Quick-Dry Technology: Lightweight fabric that doesn't get heavy when wet and dries rapidly after a wash.
-
Reflective Detailing: Increases visibility on early morning and evening winter walks.

- MMMelanie M.Verified BuyerRated 5 out of 5 stars2 months agoGreat quality, looks comfortable
Great quality materials and design is really good for both putting it on and having it comfortable around his legs.
- KKateVerified BuyerRated 5 out of 5 stars7 months agoNice vest
Rex is not overly keen on putting it on, but once on he is fine and it keeps his core warm and dry. Doesn’t stop him running around!
- KRKirra R.Verified BuyerRated 5 out of 5 stars8 months agoGenuinely the best vest ever
I bought this for my collie x kelpie, she’s 14kg and fits perfectly into a size medium. I walked her at 5am every morning through winter in the snowy mountains and she stayed toasty warm underneath but it didn’t stop her from moving freely. 10/10 would re purchase. Please enjoy video of Darby showing you her new vest.
- GGGarrett G.Verified BuyerRated 4 out of 5 stars11 months agoThermal vest
Fantastic quality, very well built. My only negative is that even though the vest is a snug fit, it tends to slip down the body becoming a hindrance for dogs front legs
- JJaneVerified BuyerRated 5 out of 5 stars11 months agoPerfect vest for a cold Hobart winter
My 13 tear old Irish girl was feeling the winter cold. The Ezyydog looked the best option to keep her warm but not impede movement and well designed. The Ezydog crew recommended the L for length which was the right call. It is easy to put on - paws in then zip up/ very quick to remove also. She can wear a raincoat over it too if it’s really stormy weather. Mouse wears her Thermax vest every day when she goes out as well as her Ezydog light, perfect for late afternoon walks and crossing roads. I highly recommend.
