For two-in-one versatility, turn to the Burton Hi-Five Mittens. The inner fleece liner is cozy and warm, and can be worn on its own if all you need is a bit of warmth for going about town. The waterproof shell is lightweight and breathable, and works well for touring missions in the backcountry when you don't want sweaty palms. Or, wear them together as one perfectly warm and weatherproof package that will have you hi-fiving yourself on the chairlift because you're just so stoked with your choice of gloves.
