Comfort and safety: Made of quality fabric with cozy cotton padding for a super soft, comfortable wear. The vest dress design provides a nopull, nochoke fit for your fur baby. Freedom of movement and adjustable fit: The harness won't hamper your pet's movements, and you can adjust the strap without hassle so it's never too tight or too loose.
