Hi Vis Reflective Night Safe Running Cycling Vest Bib by Karrimor. Lightweight Fluoro Yellow and Reflective for max visibility. Suitable for Runners Cyclists Walking Ramble Hike Bike Etc. Materials EN471 Compliant. One Size.

This is a good quality vest, but for a one size item it is smaller than I imagined it would be. If you are Large/ XL it'd be a snug fit over a top plus a jacket in the winter.

the idea is perfect ........... mesh , lightweight super reflective . Sadly , only those of 'slight build' will find it useful .I am an L or XL and to me this is too tight both at the neck and at the upper waist . Does'nt even go down far enough .It would be best if the designers made a larger one with adjustable shoulder straps and velcro or snap fasteners on the elastic on the side .. that will make it really fit all and will be easier to put on and take off . I am going to make the above modifications to the one I received as a gift from my daughter !
