When the sun begins to set the reflective collar and paw prints catch the light of headlights streetlights and other light sources providing hundreds of feet of nighttime visibility.

By fastening with Velcro our vests provide a snug custom fit and are able to be put on and taken off in just seconds because nobody said safety couldn t also be convenient!
