Packing for a 3 week winter trip requires warm clothing including coats, gloves, hats, and boots. To stay comfortable, it is important to pack layers of clothing, including long-sleeved tops, sweaters, and thermals. Necessities like a first-aid kit, sunscreen, and a good camera should also be included. For winter sports, it is essential to pack appropriate gear such as skis, snowboards, and snowshoes. Don't forget to pack a comfortable backpack for daily excursions. via @threeweektraveller
