I wear some cheap one size fits all pound shop gloves, and i used to wear some Kona MTB Gloves over them for practice. That room gets so cold we have to warm up one of the guitar amps to get it to work. Ski coat, hat, gloves, scarf and jeans fer me. I hate trying to play on cold strings, makes me thing there gonna be really brittle and snap for some reason.
