Multiple layers allow you to add or subtract clothing based on time of day, weather, activity level, and cleanliness. Three essential layers include; a base comfort layer, a warmth layer, if needed, preferably made out of water-repellent material, and a thin yet durable rainproof layer. Always pack double the socks and underwear you think you need because unforeseen wetness is a product of nature. Top your pack off with a hat and some boots; you’re already off to a great start.
