What to Wear for Survival Pack for layering - Depending on the geographic location of the wilderness area you are visiting and the time of year, temperatures can vary dramatically over the course of 24 hours.
Layer your clothing to stay warm and keep your pack light. Pack silk long johns, t-shirts, trekking pants that convert to shorts, underwear, socks, and nightclothes. A fleece jacket, windbreaker, and waterproof outer jacket should be enough to handle most conditions. Wear a good pair of hiking boots, but pack a pair of sandals and water shoes. Round out your wardrobe with gloves, hat, and a scarf.
