^^^^^this guy would know.

And I agree with Lobster Claws. My wife got me some and I wear them so she doesn't feel bad, but can't stand them above 0degF (they're that hot). Honestly, my preferred glove for above 0 is made my Kinco, and is about $6 in most feed stores. It's pigskin palmed with a proprietary insulation. I use them for mountaineering, backcountry skiing, and commuting.

Wife actually bought me some lighter-weight gloves, so I'll try those as the fall comes on, but I like really lightweight, fleece liners for anything above freezing.

Oh yeah, I have warm hands, tho.
