The Proviz REFLECT360 gilet is the first fully reflective gilet designed for cycling, running and other outdoor uses. The gilet is designed to help you stand out at night on the roads as well as be a functional and comfortable item for you to use when out exercising.  The REFLECT360 gilet will keep the wind out during the colder months yet the perforated back mesh will help the extra heat escape. About the fabric: The fabric used for the REFLECT360 range is highly technical. During daylight it is a modest grey colour. At night, when the fabric picks up an external light source, eg vehicle headlights, it gives 'astonishing reflectivity'. The material is CE EN 20471 certified.
