Made with neoprene, it dries quickly and, above all, feels incredibly good. I think it will gently fit your dog's body. It has a texture similar to a wetsuit. The cushioning is also quite high, and the soft shock absorption is a finish that is worth the effort we put into it. The urethane inside is also quite thick, so even if your dog pulls, it will absorb the impact, reducing the burden on your dog considerably. The T-shaped design also reduces the burden on your dog's neck and trachea, and the width of the cushion is wide, so the "surface area" and "high cushioning" further reduce the burden on your dog. There are two key points to the T-shaped design. First, there is a handle on the back, which is very convenient when your dog suddenly pulls. The handle area has thicker fabric, making it easier to hold. Second, it's easy to put on and take off. You just put it over the head and fasten the buckle without lifting the legs. It's very easy, so you can put it on or take it off in a few seconds. Ease of use is a big plus when you're in a hurry for a walk (lol). Oh, and we use high-quality YKK buckles, so there's no compromise there either. Chest circumference: 65 to 85 CM, Width: 5 CM
