When you ride your bike in a large city you need an intelligent co-pilot. This revolutionary cycle jacket has a higher IQ than most drivers which will go a long way to keep you safe. It features a couple of dozens of built-in high intensity LEDs and proprietary iMASS turn indicators that activate when youre about to turn. As you stick out your arm to signal your move (or even if you keep both hands on the handlebar) motion sensors will light up your sleeve like a Christmas tree. When the turn is completed the sensors will self-cancel after five seconds. The LEDs on the back and front on the jacket ensures your visibility in pitch black rainy or foggy conditions. The jacket is made of Dupont Teflon®-coated rainproof and breathable fabric and features all round ventilation. Its powered by the included USB rechargeable Lithium-ion battery. Machine washable though you must remove the battery first.
