Good fo cold days.
Haven't had a chance to use yet. Too much snow right now. :)
The hand warmer if handy and keeps my hands warm. I use them while playing golf. It allows me to push my golf cart and hold onto the cart handle as well. I keep the warmer hanging on the cart handle. That way when I'm walking I just slip my hand(s) inside to stay warm plus be able to control my pushcart. I only wish the warmer was larger to accommodate easier entry of my hands into the sleeve.
