I don't do a lot of product endorsements, and I've never received compensation of any kind for any product I've mentioned on this blog (and I won't be starting now.) But I have to say that these gloves really do the trick. I've been cycling in Maryland winter weather this season in weather as cold as 20° F. (-7° C.) and have yet to see the weather that these gloves (along with simple polypro glove liners) can't handle. These gloves are not cheap -- they cost $55 to $65 depending on your source. But comparing that cost to circulation difficulties and attendant possible neurological problems, these guys seem like a bargain.
I call them my "Zoidbergs".
