We designed the LED Running Vest with serious runners in mind. Made of lightweight, water-resistant mesh, its two illuminated flexible polymer strips (front & back) can each be set to one of two bright LED modes (steady glow or flash), and the sides are trimmed with 360° passively reflective safety accents. The power/mode buttons are easily accessible on the front and back of the vest, and easily adjustable straps at the waist can be cinched for a precise fit. Two zip closure pockets in the back are individually sized to hold everything you need for your run, with one of the back pockets featuring a weather-resistant design to keep your cell phone or other valuables safe if you get caught out in the rain. There's even a handy key clip for your home or car key.
