The High-Vis Belts can adjust from 26″ to 90″ (66cm – 230cm), enabling it to be worn in Summer (e.g., over a T-shirt) or in Winter (e.g., over a parka).   A robust nylon buckle can function smoothly in virtually any environment and a side-release design makes it easy to open and close.   We have incorporated a “hook and loop” breakaway feature into our reflective belt so it will open and come off should it get caught on a vehicle, machine, etc.
