I bought these for riding my bike this winter, when it gets colder and fingerless gloves are not such a good idea. I have small hands (size 8 I think) but I bought the medium. They fit well, a little extra room, not really snug tight, but the extra airspace seems to make them a little warmer. I have used them several nights on the bike down to around 40 deg F and they do the job quite well, hands were warmer than inside a heated building. Fleece back is soft and convenient in case of runny nose or drooling and the velcro fastener tab keeps the gloves on, without making them hard to take off. Well made and worth the money.
