My hands sweat in these, but they are pretty good. I actually wear these down to 35F, but lower than that, my thumbs get really cold.

I have these for 50-65F:

I really like the comfort of these gloves for this temp. They breathe nicely and tho my hands still sweat, they fell comfy.

I wear an XS in gloves...
