Does your dog struggle with the heat? Don\\\'t stay in, keep your dog comfortably cool in a durable vest that uses natural evaporation. Three layers work together to beat the heat. The outer layer wicks moisture and reflects heat. The middle layer stores water which will evaporate and create a cool surface. The inner layer transfers this cooling effect to your dog\\\'s body.

Reflective trim for visibility and light loop for attaching battery-powered light. Determine fit by measuring around the deepest area of the chest. In grey. 100% polyester. Washable.
