M size is approximately 33-38.1cm (13-15 inches) for chest circumference and 22.9-27.9cm (9-11 inches) for neck circumference. 【Very Soft and Comfortable】The harness uses lightweight, soft, and breathable air mesh fabric. The edges are soft and cushioned, effectively preventing injuries and providing comfort and protection. This all-weather pet vest is not too thick, so it doesn't hinder your pet's movement and won't get too hot on hot days. It's securely sewn, so you can walk your pet with peace of mind. 【Increased Safety and Ease of Use】This harness reflects surrounding light in any dark place, maximizing visibility during nighttime runs. It also has a sturdy D-ring on the back for attaching a leash. The vest-type design evenly distributes the force from the leash from the chest to the shoulders, preventing choking and neck stiffness. It is much more comfortable and safer than traditional halter harnesses or H-type harnesses. 【Note】Please check the size in the actual product images before purchasing! ＼ * The product is unused, but because it was a gift, it is listed as "Like New"! * Immediate purchase is welcome, and silent purchases at midnight are OK◎ * Only one item, first come, first served! * Bulk purchases are welcome, please feel free to comment♡ * Free shipping!
