I dunno, Nathan, it sounds to me as if you're doing the right thinglayering up and putting on a waterproof outer glove. Maybe you suffer from Raynaud's Syndrome, a condition that leads to cold hands? It's more common in women, but hardly unheard of in men.
Otherwise, all you can do is keep trying to find a really warm glove. Or a mitten. Mittens are much warmer than gloves, but of course you lose some dexterity. A compromise product is Outdoor Research's Mutant Modular Mitt ($150; www.orgear.com). These are heavy-duty mittens with a Gore-Tex shell, but complete with separate forefinger openings so they can interact with the thumbs on their own. Along with the extra dexterity they afford, these are warm, warm, warm glove/mittens (mittoves? glittens?).
Beyond that, there are some chemical hand-warmers that can be inserted into a glove. Grabber makes one called the Mini Hand Warmer, which goes for about $1.50 apiece and can last up to six or seven hours (www.grabberwarmers.com). You might also find some new versions of those classic hand warmers that ran off lighter fuel. That's right, you lit these things then stuck them into your gloves. (The flame was of course enclosed.) I noticed Restoration Hardware was selling these almost a year ago for about $5not sure if they still are, but I know eBay has some of these things available. Give one a try if the Mutant Mitts don't do it for you!
