“Watching my dogs struggle in the Aussie heat, especially without power or air con, is why I created the Coolaroo Cooling Vest.” Jo, Founder

Howltrek in action

Description

Beat the heat, without missing a single adventure.

Aussie summers don't slow your dog down and now they don't have to. The Coolaroo Cooling Vest uses advanced evaporative cooling to draw heat away from your dog's body, keeping them comfortable for hours on the trail, at the beach, or in the backyard.

No gimmicks, no batteries, just soak, wring, and wear. As the water slowly evaporates, it creates a natural cooling effect that can last for hours, and re-soaking takes seconds when it starts to dry out.

Lightweight, breathable, and built with an integrated harness, it's designed to go wherever your dog does, from lean trail runners to couch-adventurers of every size.

How to Measure your Dog.

find the perfect fit

How to Measure Your Dog for the Best Fit
Use a soft tape and measure:
Neck: Where the collar naturally sits.

Chest: Around the widest part of the ribcage, just behind the front legs.

Length: From the collar line down the spine to the tip of the tail.

Find the corresponding size from chart below.

Every dog is built a little differently, from lean trail runners to couch adventurers. Note: The vest does not necessarily need to reach all the way to the tail. If in between sizes, size up for comfort and better cooling coverage.

How long does the cooling last?

The cooling effect lasts for several hours, depending on the heat, humidity, and how active your dog is. When it starts to dry out, just re-soak, to recharge. No need to remove vest, just pour water over the vest for an instant refresh.

Is the vest suitable for all dog breeds?

Yes! The vest comes in 6 size-inclusive options and is designed to fit a wide range of dog breeds, from small companions to large, adventure-ready dogs. For best results, check the size guide and measure your dog’s chest, neck and length.

Can I use it as a regular harness?

Absolutely. The Coolaroo Cooling Vest features an integrated harness design, so there’s no need to layer a harness underneath. It offers secure attachment points while keeping your dog cool and comfortable. For strong pullers, we recommend using a collar for extra control.

Can my dog wear it daily?

Yes. The vest is made from lightweight, breathable materials suitable for everyday wear in warm weather. Just be sure to keep it clean, properly fitted, and re-soaked as needed to maintain the cooling effect. It also works beautifully as a sun-reflective layer for dark-coated dogs, helping reduce heat absorption even when worn dry.
