Extremely warm! Even when temps were in the teens! Mind you, you still need to layer up your regular clothing, but these gloves kept my fingers nice and toasty for hours as I worked in the barn. I haven't tried riding in them, but I don't think they're too think for just pleasure riding/trail riding. Wish they were water proof, but the few times I've splashed water on them I haven't had a problem. Just wouldn't let them get soaked.
