I got these for when I go snowboarding at night mostly because it's a bit colder than the day, and I wanted another layer when I took off my mittens to attach/detach my leash. So I've been wearing them under my gordini mittens---and it's been sooo warm!! such an improvement. I'd highly recommend for chilly hands. The only thing is that the right glove seems to be a little smaller and takes a little longer to get on, but not a problem in the big scheme of things. They are cold when worn by themselves since they don't have any windproofing, but help your hands warm up quickly and stay warm in another pair of gloves. And as far as I know, the size chart is accurate--it's what I based my order on and the smalls fit well for me. I'm overall really happy with the purchase!!
