One coat. One harness. Zero faffing.
A rugged two-in-one harness-vest combo for cold-weather exploration
Cold, damp walks? Muddy adventures? That moment when your dog gives you the look because apparently putting their coat AND harness on is a personal insult?
Meet the Ruffwear Overcoat Fuse Insulated Vest — a clever two-in-one dog coat and harness designed to keep your dog warm and ready for whatever the weather throws at you.

This isn't just a cosy coat. Ruffwear has built a proper harness into it, so you can slip it on, clip your lead straight on and get out the door. No wrestling with a harness underneath a coat. No awkward layers. No “where's the harness gone?” moments.
Just slip on, clip in and go.
Why your dog will love it - Warm where it matters
The Overcoat Fuse combines a rugged, weather-resistant outer shell with high-loft recycled insulation to help keep chilly dogs warm on cold-weather walks and adventures.
Inside, there's a soft fleece lining for an extra cosy feel, while the durable outer fabric helps shrug off light moisture and the general abuse that comes with being a dog who believes every hedge is worth investigating.
The harness is built in
This is where the Overcoat Fuse really comes into its own.
The integrated harness gives you two leash attachment points:
- Back attachment – a strong aluminium V-ring for everyday walking
- Front attachment – a reinforced webbing loop to help redirect dogs who like to pull
So if your dog normally wears a harness underneath their coat, you can simplify the whole process.
Coat on. Lead clipped. Adventure activated.

Little pockets. Big usefulness.
There are also two zipped pockets, perfect for carrying a few little essentials such as poo bags, treats or whatever else you normally end up stuffing into your pockets.
Because apparently dog walking requires the equipment list of a small expedition.
Built for proper dog adventures
Ruffwear doesn't really do sit beautifully on the sofa and look pretty - we aren't here to sell you fashion over function.
The Overcoat Fuse has a durable, abrasion-resistant outer shell designed to cope with cold-weather adventures, undergrowth and all the other things your dog considers essential to a good walk.
Reflective details help improve visibility in low light, and there's even a loop for attaching a Ruffwear Beacon safety light.

Who is the Overcoat Fuse for?
It's a brilliant choice for dogs who feel the cold, short-coated dogs, older dogs, dogs who love winter adventures — and anyone who is fed up with trying to put a coat over a harness.
It's particularly handy for those chilly autumn and winter walks when you want your dog warm without piling on layer after layer.
And let's be honest, anything that means less faffing before you leave the house gets a big Bob thumbs-up (or paws-up, actually!)

Getting the right size
Ruffwear sizes the Overcoat Fuse by your dog's chest girth, measured around the widest part of their rib cage.

It is VERY important that you measure your dog when buying clothing as all brands size differently. Ruffwear tends to size large, so don't assume you know your dog's size based on other brands you may have purchased.
