Might work for balmy California but before you try to sell these as actual warmers and gouge a person for $150 make sure they actually warm.I bought the heated insoles the night before deer hunting charged them over night and didnt need to turn them on until a couple hours after I got to the stand. powered them on and nothing. I got back to the car later in the afternoon and took them out and turned them on and after sitting for a half hour in the passenger seat they were lukewarm at best. WASTE OF MONEY AND TIME!

Heat Factory USA makes awesome hand warmers. Whether its for camping or going to a Padre Game, their product always comes in handy. They also have two super cute pups at their office.

Heat Factory USA is a family owned business... they have amazing customer service. Everytime I come by the office I am always greeted with warmth and kindness. Thank you for all that you do.

Great company with quality products.
