I purchased the heated vest for golfing during the winter here in Houston. I have used it twice so far and found it to be perfect for temperatures in the 40's. Otherwise I would have to wear too many layers and that restricts the golf swing. By having the 4 settings, I was abled to adjust the temperature when the weather warmed up during the round. I started at 75 % setting and went down to 25% setting. It more than lasted a 5 hour round. I also used it once while watching my grandson's soccer game and again, it tamed the cooler weather. Highly recommended for taming the weather and not having to wear heavy clothing.
