This is a warm glove if it doesn't get wet. The initial fit is a bit small, but it stretches nicely after a few wearings.
The neoprene cuffs are great and fit nicely under jacket cuffs. The leather is supple and feels thin, but not in a bad way. The gloves are warm for me to 0 degrees, but I've been lucky to have hands that don't really get cold easily.
It's a great looking glove, but if you're going to use it in the snow a lot you need to find a good sealant or waterproofing wax. The waterproofing goop that comes with the gloves is essentially worthless. Snow melts and soaks into the gloves pretty easily, and even though the gloves are warm, the water eventually gets to your fingers and things go south from there. When it's really cold, the snow melt isn't as big a problem and the gloves stay mostly dry and warm; but when temps are around or just below freezing, these gloves don't perform well. I've had success with Sno-Seal as a way to keep these gloves water resistant and dry; apply early and often to warmed gloves.
If you really want bomber gloves that keep your hands warm and dry in cold and snowy conditions, these are fine if you pay attention to waterproofing; otherwise, find some with Gore-Tex.
UPDATE: So, after two seasons with these gloves, the stitching has come out of one fingers, making a nickel sized hole where the seam between the leather pieces has come apart. Not sure what their warranty policy is, or if my experience is typical, but if you are looking at these just know that they may begin to fall apart in the latter part of the second season. Also, per Karim's comment below: of course all leather gloves soak up water. My comment is about the waterproof wax that comes with the gloves--it is worthless. Find some Sno-seal to use instead.
