I inherited a pair of chopper mittens from my dad. They're heavy and thick but they're warm and durable as anything, bit of a trade off. They consist of a heavy wool mitten with a leather shell. Here's a website I found that carries them for $48 dollars you can get both the liners and the leather shells, not bad compared to something similar made of goretex and thinsulate. http://www.berlingloveco.com/admitdeercho.html They're just about exactly what I have. They're warm, but they're also pretty clumsy.
