To prevent getting too cold, wear proper clothing and shoes, such as:

• A hat and face mask.
• Layers of clothing to keep you warm and dry.
• Clothing made of moisture-wicking fabrics, such as wool, polyester, or nylon (not cotton). These are good insulators and will prevent loss of body heat even when the fabric gets wet.
• Wind- and waterproof outer layers to keep you dry.
• Wool or synthetic (not cotton) socks and waterproof boots that fit well. Socks, boots, and shoes must fit closely but not be tight or have any pressure areas. Smooth out all wrinkles in your socks when you put them on.
• Mittens rather than gloves so your fingers are together and can be rolled into a fist.
