A visible dog is a safe dog. That's why our safety vests pull double duty, universally designed to be bright day or night! The tough, lightweight neon yellow nylon provides superlative daytime visibility, which makes it great for walks in the woods and hunting. 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.
