sleeping body. These mats are comfortable, lightweight, and provide excellent insulation. They
are usually available at discount stores and price clubs, but you will find a better selection in
specialty backcountry stores. When snow camping, I like to combine a short closed-cell foam
pad (can't puncture or deflate, and won't compress under your hips and shoulders to make a
cold spot), placed under my midsection, along with a full-length self-inflating pad, for out-
standing thermal insulation combined with good comfort.
Backpacks
If the need arises, a large-capacity pack (at least 4,000 cubic inches, and preferably over 5,000
cubic inches) can help you transport your gear, food, and water on foot. The traditional frame
pack, with a rigid welded frame of tubular aluminum, is best for carrying maximum loads. Per-
sonally, I prefer the mountaineering-style soft packs, with internal molded or bendable frames,
because they allow more freedom of movement for traveling over rough terrain, plus they stuff
better into car trunks or other tight places. Whether you choose an internal or external frame
model, a good, comfortable, padded hip belt is essential to take some of the load off your
shoulders. Proper fit is also important. If the pack is too long or short for your torso, you will
have a hard time adjusting the hip belt and shoulder straps to distribute the load properly. Some
recommended manufacturers of mountaineering packs are Osprey, Dana Designs, North Face,
Arc'teryx, and Lowe Alpine. Specialty backcountry stores will have the best selection.
