The Reebok LED Running Vest is an ideal safety vest for those people training outside. It has removable LED lights on the front and back to help you be seen in the dark. The hi-viz vest is made from breathable material and has a generous cut so it will not impede your movement as you exercise. A simple hook and loop closure makes it easy to put on and take off. Available in a choice of size: either S/M or L/XL.
