Since I ride all year long here in NY. I decided to buy a pair of 7.5V battery operated heated gloves this winter. I purchased the Venture brand heated gloves. They're decent, but even the highest setting doesn't really keep my hands warm while riding in 30 degree temps. I'm guessing the 12V plug in type would do a better job. Rather than return them I bought some Little Hotties Hand Warmers and stuck one in each glove, and wow what a difference those things make. I slid one in each glove on the top side of my hands and they heat up the entire inside of the glove. I figure the heated gloves helps my finger tips stay warm so I still keep them on Med heat. I bought a box load of Little Hotties at Costco for $12 so I should have enough for the entire winter. Between the heated gloves an the Little Hotties my hands won't freeze this winter.
