Hi Dar,
It's so cold here now (in the 20's daytime) that I ALWAYS wear layered gloves outside now- so I've only tried them layered with a wool liner underneath AND a big ski glove over them as well. In that respect they are doing what I wanted them to. Hard to tell how they'd be just on their own!
They do seem nicely made though, and they look stylin' in a techno way.
