These gloves are warm without the bulk. The rain barrier also keeps the wind out. They aren't too thick so no dexterity issues. I do sweat in them some if climbing a lot but they do a pretty good job maintaining warmth even damp. I have found these to be the gloves I grab when the temps are 45 to about 55. If it's going to get warmer, I usually take so lighter gloves to switch out.
I really want to like these gloves... but they're just not warm. My hands get cold wearing these when its 40-50 and I end up needing to ball my hands into fists inside the gloves as if they're mittens. I have a pair of castelli neoprene gloves that are about the same for warmth though they don't breathe as well as these. The waterproofing works well and they go through the washing machine well.
