1. Ruffwear Swamp Cooler Vest
A 3-layer evaporative cooling vest that activates with water: soak it, wring it out, and place it on your dog. The light-colored fabric reflects solar radiation while evaporation pulls heat from the dog's back, chest, and belly. Compatible with Ruffwear Front Range and Web Master harnesses via a lead portal.
…so your dog can hike, run, or play in hot weather without overheating — especially valuable for dark-coated and brachycephalic breeds.
Honest downsides: Effectiveness drops significantly in high humidity where evaporation is slow. Needs re-soaking every 30–60 minutes in intense heat. Some users report the fit is narrow for barrel-chested breeds. The M size runs long on some dogs.
