Use the date gloves under my motorcycle winter gloves. always drive by scooter had ever since dead finger with gloves that fit under the gloves can also at -10 ° C without a drive drop the finger. a glove had broken after a few months but was replaced a quick and easy the battery will last about 1.5 hours at full capacity approx. also needs something forever up but it is full just has to be charged overnight. I am happy about this as an alternative to gloves a multiple more expensive heated motorcycle gloves
