UYN LUMINANCE is the ultralight jacket designed for night running or low light conditions. To make it, we have used the special phosphorescent HI-GLOW membrane which glows in the dark for about two hours and recharges when exposed to sunlight or artificial light (no LED). In this way, the runner wearing the Luminance jacket is clearly visible in the dark. The waterproof fabric provides greater protection from light rain, the inserts at the shoulder blades allow body moisture to escape thanks to FLOWTUNNELS ventilation technology. Luminance is engineered to be easily folded away: the packable design allows you to carry it comfortably with you, always ready for use.
