Stay visible with our Reflective Gear! In this set, we have included two high quality reflective vests; one for you and one for your best friend (your canine companion).

The dog vest adjusts both around the neck and waist to size with the help of velcro. The reflective vest for humans can be adjusted over the shoulders and around the waist - one size fits most. 3M REFLECTORS: The reflectors on the vests are made of high quality 3M material. 3M reflectors are tested and are proven to meet the Personal Protective Equipment Standards (or PPE) set forth by OSHA.
