I generally just use gloves. I can change over my split (with Sparks) without removing my gloves. If your hands get really cold, you may want to try a mid weight pair of gloves for the hike up and switch out to your mittens for the down ride, if that is what you like. Regardless of how you do it, I would definitely have a back up pair of gloves or mitts in your pack. It can save your day. I would also recommend having an extra pair of goggles. Those are two items that if they go sour on your can really make your day miserable. Having spares can help keep your day pleasant.
