Pack warm and protective clothing: coats, insulating shirts, gloves, hats, scarves, and boots. Bring accessories like sunglasses, sunscreen, lip balm, and hand warmers. For skiing/snowboarding, include skis/snowboard, helmet, goggles, poles, and snowshoes. Essentials like a backpack, reusable water bottle, snacks, money, and documents are key. Lastly, don’t forget your phone and charger for communication and entertainment.
