The newly redesigned Adventure Cooling Vest is a lightweight cooling vest made for dogs on the go, helping to keep them cool on outdoor adventures. The vibrant color detail and reflective material also helps keep them visible on walks – especially in low-light conditions. Constructed from durable ripstop fabric, the stylish redesign features two secure points of closure at the stomach and chest. Long-lasting cooling polymer crystals, which are sewn directly into the vest, absorb water and slowly evaporate to help keep dogs cool for up to 9 hours. To activate cooling features, simply soak vest in water for 5 minutes before use. Squeeze out excess water. For maximum cooling, soak in ice water before use. Lay flat to dry, do not wring. - available in teal or pink trim - comes in 3 sizes (see sizing below) Small: 16 - 24"" in girth Medium: 23 - 32"" in girth Large: 30 - 40"" in girth " *Actual product's colors may vary slightly from the images shown on our website
