Okay this has probably been mentioned before but like seriously I need some gloves that are insanely warm. My fingers are like long and slender. Perfect for getting immensely cold in the winter because of this. So what I'm asking is I'm tired of buying gloves and having my hands freeze after like 3 hours of skiing. I need something that will be able to keep me warm for up to 12 hours of skiing at a time. Anything anyone knows of that will do the trick?
Not very much. You're partly paying for the brand name. And, BD and Arc do have incredibly build quality and put a lot of time into developing their products.
OR and Swany are still excellent choices. I rocked Swany gloves for a while and really liked them. They're incredibly warm and still pretty dexterous. Most of their models also have a small waterproof zippered compartment that's pretty clutch for a handwarmer in gnarly conditions.
The other thing I would recommend if you're trying to do this cheaply would be to buy some silk or capilene glove liners. They're very thin material that you can easily wear under your normal glove but can make a big difference. Layering is really clutch for warmth.
But as a standalone glove I think you'll be happy even if you don't drop 150-200$ on gloves from Arc or BD and get a Swany glove. I'd recommend Swany.
If you're willing to spend the money, Hestra is a very nice glove. I love mine. As long as I can keep them on my hands and keep the snow out of them, they're really warm. But I fiddle with my iPod a lot. Even when they're damp inside they keep my hands pretty warm though.
