Hi Kathi- well oddly enough I have BOTH those items...they happen to be the only Ibex glove items I have, so don't be thinkin' I have them all now!
I got the Climawool glove in 2006 and wore it a lot last winter. It has a lot of nice features, but will not keep my fingers from getting cold on my bike if it's 35 or below UNLESS I wear 1 or 2 glove liners under them. I have not found a glove yet that can do that without liners for biking.
I just bought the Loden mittens and have not had the opportunity to try them out yet. It's not very cold here right now. (30's, 40's). Of course you are in VA and might not need gloves for 20 degree conditions.
Both these items I purposely got a bit large so I could wear other thinner gloves under them. Both of them also have no trouble keeping me warm when snowshoeing or fitness walking down to 10 degrees. It's the wind when biking that's the killer. One combo I use is a pair of thin soft cashmere ladies' gloves or merino glove liners, then my Gore Volcano windstopper gloves (not bulky), then the Climawool glove. This i would typically wear for a 2 hour bike ride at 30-40 degrees. I got the loden mittens for the most severe cold, to wear over other gloves too that same way. Can't wait to try them out- the loden is nice and thick and soft wool.
