Ruffwear Swamp Cooler Harness for Dogs

When the temperature rises and the trail keeps going, the Ruffwear Swamp Cooler Harness keeps your dog in the game. A trail-ready, all-in-one cooling harness, it integrates Ruffwear's proprietary Swamp Cooler technology directly into the three-strap harness platform — cooling from the core while keeping your dog clipped in and ready to move.

Why the Swamp Cooler Harness?

The Swamp Cooler Harness solves a real problem: keeping active dogs cool in hot conditions without stopping to apply separate cooling gear. Swamp Cooler technology works through evaporative cooling — wet the harness, wring it out, put it on, and go.

The moisture pulls body surface heat away as it evaporates, providing a measurable cooling effect during the activity. Six points of adjustment allow a precise, comfortable fit, and the quick-grab handle is always there for lift-and-assist. Two leash attachment points keep your connection options open on any terrain.

What Makes It Work

The outer layer is bluesign approved polyester air mesh for breathability and evaporative efficiency. The middle layer is polyester felt — the Swamp Cooler technology layer that holds water and releases it gradually to drive the cooling effect.

The lining is bluesign approved dry-weave polyester mesh to manage moisture against the dog's skin. Webbing is nylon. Buckles are bluesign approved ITW Nexus Mach 1 side-release. Leash connection is an anodised 6061-T6 aluminium V-ring. Made in Vietnam.

Suitable For

Ideal for hot-weather hiking, trail running, and any outdoor activity in warm conditions. Best used when temperatures are high enough that evaporative cooling provides meaningful benefit. Available in 2 colours, 5 sizes. This product is non-returnable due to hygiene reasons.

How to Use

Before use in hot conditions: submerge the harness in water, wring it out thoroughly so it is damp but not dripping, then fit on your dog and go. Re-wet as needed during the activity.

For fitting: loosen all straps, place on your dog, fasten all six buckles, and adjust until snug with two fingers fitting beneath each strap. Attach your leash to the V-ring. Hand wash with mild detergent after use, air dry completely before storage.
