Derby Originals Hydro Cooling Dog Jacket – Reflective Evaporative Cooling Vest with Adjustable Belly Band & Harness Opening, Lightweight UV Protection Coat for Hot Weather & Outdoor Dogs

Derby Originals’ innovative Hydro Cooling Dog Jacket was designed to help keep dogs safer, cooler, and more comfortable during hot summer weather. Using advanced evaporative cooling technology, this lightweight jacket naturally cools your dog for hours without bulky materials or ice packs.

Simply soak the jacket in water, wring it out, and place it on your dog. As the water slowly evaporates, it creates a powerful cooling effect that may help reduce overheating and heat stress during walks, hikes, outdoor events, training sessions, or everyday summer use.

This upgraded premium version features an adjustable cooling belly band that helps cool your dog’s chest and belly area while providing a more secure fit for a wide range of breeds and body shapes. Reflective trim improves visibility in low-light conditions, and the built-in harness opening allows convenient leash attachment without removing the jacket.

The lightweight 3-layer construction was specially engineered for performance:

• Outer layer helps reflect heat and encourage evaporation
• Middle layer absorbs and retains cooling moisture
• Inner layer stays soft and comfortable against your dog’s coat

Perfect for:
• Summer walks & hikes
• Dog sports & agility
• Camping & outdoor events
• Beach trips & travel
• Protection from UV rays & overheating
