Constructed to provide buoyancy, along with a cozy secure fit, the Paws Aboard Doggy Life Jackets features an advanced breathable mesh underbelly for proper draining and drying, which provides your dog more comfort and healthier conditions than traditional pet life jackets made with neoprene, which can cause heat exhaustion and chafing. Our "Nautical" design makes our newest Paws Aboard Designer Doggy Life Jacket a perfectly safe outfit for hanging out on the deck or the dock.
