Bought this on an Instagram whim and just hoped for the best. These hand warmers are golf game changers. Simply hold the bar inside as you go to the next shot and your fingers are toasty. I could imagine that any sport that uses touch or feel with the hands would benefit from these.
Took these bad boys to Alaska for training. Kept the hands warm. Good battery on low power. Even with battery off still kept the hands warm.
I bought this blue GTech “fanny pack” hand warmer as a 2024 Christmas gift. I have owned one for several years in black. I discovered this LIFE SAVER of HANDS on the Reynaud’s Association Marketplace. Reynauds is a health condition were you hands and feet turn blue when in a cold environment, both outside cold and A/C cold in summer. Therefore, I use it year round. What can I say I love it, Love it, LOVE IT!
