Staying warm on the mountain while skiing requires a layered approach to clothing. Start with a moisture-wicking base layer to keep sweat off your skin and maintain warmth. Follow with an insulating mid-layer, such as a fleece or down jacket, to trap body heat. For protection against wind and snow, an outer shell jacket and pants are essential, offering waterproof and breathable qualities. Don’t forget warmth accessories like a hat, gloves, neck gaiter, and ski socks to protect extremities from the cold. With the right layers and accessories, you can stay comfortable and focused on the slopes all day long.
