Mens S1 Run Vest is a running vest for men - not too warm and not too cold, but just protective enough that you can adjust the insulation to the weather with the layer you choose underneath.
The vest has a windproof and water-repellent front and a mesh panel on the back for maximum ventilation. The inside of the collar is soft and moisture-wicking.
The vest has a sturdy zipper with a windproof back and a zippered pocket on the front with an elastic back that adapts to the contents of the pocket - for example, phone and bank card.
Discreet but safe 3M reflective tapes on the collarbone and back ensure 360 degree visibility during the dark hours. If desired, choose the vest in Hi-Vis for more safety.
