Snowboarding for the first time in February, what all do I need?

The crack is nothing to worry about. If your boots fit well that's good. What you will need: thermal( under armor). Long sleeved tshirt. Hoodie and a good winter jacket. Sweat pants. water proof snow pants, socks that come ABOVE the top of your boot. Don't want bad blisters. Water proof gloves. Neck guard. Like a scarf or bandana. Anything goes. Possibly goggles. I recomend a helmet for your first time. But your choice.
