In addition to the main layers, other gear like gloves, hats, and socks play a critical role in maintaining warmth and comfort. Insulated, waterproof gloves are essential for keeping your hands warm and functional. A good hat, preferably made of wool or synthetic material, will efficiently trap heat and provide protection against the elements. Socks, often overlooked, are vital for foot comfort and health, especially during long treks. High-quality, moisture-wicking socks will prevent blisters and keep your feet dry and warm.
