This is an absolutely stupendous jacket. Extremely well designed, engineered and constructed. The fabric is soft and lightweight, yet replete with hidden hood, liner, and lighting system. The yellow colour dramatically stands out during the day, and as lit up at night, makes one extremely visible. One feels instantly safer - day or night. The easy to recharge battery is unbelievable tiny, yet powers the led system for hours. For cyclists and runners, this jacket rocks. People stop me to ask where they can get one. It is a marvel. I don't know how it could be so well engineered and sewn for the price. If there is one piece of clothing you will want to have on, this is it. Safety envelopes. A gotta have!
