The Alpha 360 Collar is our take on sustainability, comfortability, and safety on everyday dog walks. Just like every Woolly Wolf product, this collar is made of recycled PET bottles. The collar has a wide fit padding with a soft and lightweight double mesh construction that conforms your dog's neck for maximum comfort. Additionally, it features a safety locking mechanism with a large yet lightweight O-ring attachment, enhancing both safety and convenience. Keeping your furry friend safe at all times, the 3M reflectors are placed on both sides of the padding to increase visibility in the dark. Moreover, the padding also includes a double loop with an additional 3M reflector, designed for attaching a LED light or a name tag. Bring comfort and safety to your everyday adventures with the Alpha 360 Collar - where functionality meets sustainability. 100 % Recycled Polyester (RPET) Ultra-light double mesh for extra comfort Aluminum O-ring attachment Duraflex buckles and plastic adjustmen
