>>2996022Just bundle up, motherfucker.
I just use regular hiking boots, and wool socks. Jeans with sweat pants under them. Shirt, hoodie, jacket.
For my hands, I use thin gloves plus pic related over them (you can just stick one finger out if that's all you need).
I've had several DSLRs out in bitter cold, and the only issue has been sluggish LCDs, and only on older models.
