Product Description Made with neoprene, it dries quickly and, above all, feels great on the skin. 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 finished to the point where it was worth the effort to be particular about 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" and "high cushioning" are likely to significantly reduce the burden on your dog. There are two key points to the T-shape. First, there is a handle on the back, which is very convenient when your dog suddenly pulls. The handle is made of 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 so easy that you can put it on or take it off in a few seconds. Ease of use is a big plus when you're busy walking your dog (lol). Oh, and the buckles use high-quality YKK buckles, so there's no compromise there either.
