The Swamp Cooler harness merges Ruffwear’s evaporative cooling fabric with everyday leash control, so you are not juggling a separate cooling vest and walking harness on hot days.

Soak, wring, and walk — then re-wet when the fabric dries. It shines on warm neighborhood miles and light trails where you want cooling without full backpacking kit.

For long pack-carrying hikes, you may still prefer a dedicated hiking harness or pack and use a cooling vest as a separate layer.
