Features and Design

The Swamp Cooler™ Cooling Dog Vest is designed with Ruffwear’s Swamp Cooler™ Tech, which employs evaporative cooling to keep dogs comfortable in warm conditions. The vest works by soaking it in water, which activates the cooling technology. As the water evaporates, it draws heat away from the dog’s body, creating a cooling effect similar to the sensation of stepping out of a lake.

Key features include:

  1. Light-Colored Fabric: The vest’s light-colored fabric reflects solar radiation, reducing the amount of heat absorbed from the sun. This is crucial for dogs with dark fur, which can absorb more heat.
  2. High Coverage: The vest provides extensive coverage, protecting your dog’s back and chest from direct sunlight.
  3. Evaporative Cooling: The vest’s core technology relies on soaking it in water. As the water evaporates, it cools the dog, making it ideal for hot and dry climates.
  4. Side-Release Buckles: These make it easy to put the vest on and take it off, ensuring a snug and secure fit without causing discomfort.
  5. Leash Portal: The vest can be worn over a harness, thanks to a convenient leash portal, making it compatible with your existing walking gear.
  6. Improved Materials: The latest version of the Swamp Cooler™ features an updated external air mesh for better abrasion resistance and improved water absorption. The new construction retains more water in high-exposure zones, extending the cooling effect.


The Swamp Cooler™ Cooling Dog Vest excels in its primary function of keeping dogs cool in hot weather. Here’s how it performs across various parameters:

  1. Cooling Efficiency: The evaporative cooling technology works remarkably well. After soaking the vest, it can keep a dog cool for a significant period, depending on the ambient temperature and humidity. In dry conditions, the vest stays effective for hours before needing a re-soak.
  2. Comfort and Fit: The vest is designed to fit snugly without restricting movement. The side-release buckles allow for easy adjustments, ensuring that the vest remains secure during walks or runs. Dogs seem to appreciate the added comfort, often appearing more energetic and less fatigued when wearing the vest.
  3. Durability: Ruffwear has a reputation for durable products, and the Swamp Cooler™ is no exception. The improved air mesh is resistant to wear and tear, making it suitable for rough outdoor activities. Whether your dog is running through brush or rolling on the ground, the vest holds up well.
  4. Ease of Use: Using the vest is straightforward. Soak it in water, wring out the excess, and put it on your dog. Re-soaking is quick and easy, making it convenient for extended outings.


Priced competitively for high-quality dog gear, the Swamp Cooler™ Cooling Dog Vest offers excellent value. Its durable construction and effective cooling capabilities make it a worthwhile investment for dog owners who frequently take their pets on outdoor adventures. Additionally, the peace of mind knowing your dog is comfortable and protected from heat stress is invaluable.
