Does anybody have any experience with any of those battery powered heated jackets/vests/gloves/socks/pants? My grandfather is getting a bit older and doesnt like to go out as much as he used to because of the cold. I'm thinking something like this might be helpful but I'm hesitant to buy something without hearing some first-hand reviews of it.
Are they worth it? What particular brands are good?
