Cold-weather golf is tough before you find the right gear to stay warm on the course without feeling bulky. The all-new ororo heated golf vest features a 4-way stretch polyester shell, providing maximum freedom of movement for an easy swing. The ultra-thin and soft Carbon Nanotube Heating Elements are strategically placed over the collar, upper back, and left & right hand pockets. Bonus, the power button is hidden inside the left pocket for keeping a low-profile look and reducing the distraction from the light over the button.
