  Whatever the surface, pitching a tent is easy—except in wind. You just follow the instructions that come with it. With a new tent, do a practice run first to see how it goes up and to check that all the pieces are there. There are so many ways of putting up tents that detailed advice is impossible. If it’s windy, I generally stake out the end of the inner or outer tent (whichever pitches first) that will face into the wind, then thread or clip the poles into position before raising the tent off the ground. In a strong wind, you may have to lie on the tent while you do this. The more the tent thrashes in the wind, the more vulnerable it is to damage, so speed is important. Once the basic shape is established, the rest of the staking can be done in a more relaxed manner. If the site allows, pitch rectangular or tapered tents with the tail or end into the wind; keeping the door away from the wind is a good idea for cooking, too.

  It’s always better to camp on clear ground than on snow. A spring camp with pyramid and geodesic dome tents.

  Rain is not as much of a problem as wind, though you’ll want to get a tent that pitches inner first up fast. If your tent is at the top of your pack you can get it out quickly without letting too much rain into the rest of your gear. You can stand packs up under a tree while you pitch the tent. Once the tent is up you can bring the pack into the vestibule and then unpack items you need for overnight straight into the dry inner tent. You can sort them out once you’re inside too. Remember to fill water containers before taking off your waterproof clothing and getting into the tent. It’s a pain to have to put it back on to get water. Once the tent is up you need to keep the inside as dry as possible, so leave all damp gear in the vestibule or outside. You can strip off your wet jacket while squatting in the vestibule and then sit at the front of the tent with your legs in the vestibule while you remove wet pants, socks, and boots. Once you’re in the tent, put on warm clothing or slide into the sleeping bag so you don’t get cold. If your sleeping bag has gotten a little damp, getting into it will help dry it out.

  For various reasons—late starts, unforeseen difficulties, a planned site’s being full or unsuitable or having a bear around, even by choice—you may occasionally have to make camp in the dark. For this you need a good flashlight or, preferably, a headlamp, especially on dark nights or in dense forest. To avoid losing things, try not to put any gear on the ground where it could be overlooked or kicked aside. Keep everything in the pack that isn’t needed in the tent. If you’re setting up a kitchen away from the tent and when going to the toilet, make sure you know the way back to your tent. I’ve sometimes spent rather longer than I would have liked finding the tent again. From a distance in the dark, a tent can easily look like a boulder or a tree stump. Take your flashlight with you and make sure you remember the direction back.

  When striking camp, I usually pack the tent last so that it can air out and any condensation can dry. In rain, I pack everything under cover. In very heavy rain you can collapse the inner tent, leaving the fly sheet staked out, withdraw the poles, and then stuff the inner tent into its bag under the fly so it stays dry. Push the poles out of their sleeves; if you pull them, they’re likely to come apart. In very cold conditions, pole sections may freeze together—don’t try to force them apart or they may break. Instead, rub the joints with your hands until the ice melts. In bitter cold, I wear liner gloves for this so the metal doesn’t stick to my skin. If poles are frozen together, chances are that any condensation will have frozen to the fly sheet. If the fly sheet is coated with ice on the inside and frost on the outside, shake off as much of it as you can before you pack it. If the day is sunny and you have time, you could wait for it to thaw and evaporate. Wet tents can be strapped on top of the pack or stuffed into a mesh pocket.

  Once you’ve packed everything, check the site for anything you’ve overlooked, such as bits of trash, clothes hung over a branch to air, or small items like tent stakes or cutlery.

  TENT CARE

  Tents look after themselves when you’re out walking. On sunny mornings, I try to dry off any condensation, spreading the tent over bushes or on dry ground or hanging it over a length of cord or branch. If the stakes are particularly dirty, I wipe them clean. Most tents come with two stuff sacks for poles and stakes but only one for the fly sheet and inner tent. I always use an extra stuff sack for the fly, because two small units are easier to pack and it keeps a dry inner tent separate from a wet fly sheet. The easiest way to pack tents is, appropriately enough, to stuff them into their stuff sacks rather than fold them—if you habitually fold the tent the same way, the waterproofing may crack along crease lines. I always put my tent near the top of the pack so it’s accessible for quick pitching the next night. I slide the poles down one of the corners of the pack between the side and the back. Some people strap poles to the outside of the pack, but I’m afraid they might be damaged there or even fall off and be lost. Stakes tend to work their way down to the bottom when kept in the main pack, so I put mine in a pocket.

  Camping on snow with pyramid and geodesic dome tents. Be sure stakes are buried firmly, with snow packed down on top.

  Airing and drying a geodesic dome tent.

  After a trip, I hang the tent up to dry before storing it in its stuff sacks. Nylon won’t rot, but a tent stored wet will mildew, which leaves stains and an unpleasant, musty smell and may damage the waterproofing. Single-skin waterproof-breathable tents need plenty of drying time; they often appear dry while still damp, since moisture can remain in the slightly absorbent inner material. If you want to wash your tent, use mild soap and warm water, never detergent, which can damage the proofing. Poles will corrode if not dried before storage. Salt corrodes poles very fast, so if you’ve been camping near the sea, wipe them down before you dry and store them.

  WILDERNESS SHELTERS

  Many wilderness areas have unlocked shelters for walkers to use. These usually provide shelter from the elements but no more, so you’ll still need a sleeping bag, pad, stove, and warm clothing. On some long-distance routes, such as the Appalachian Trail, walkers can use shelters almost every night. I generally prefer the freedom and solitude of a tent or tarp, but in bad weather such shelters can be a blessing. I always like to know where they are in case I need them. It’s best not to rely on them, though; they may be full.

  SNOW CAVES

  In deep snow you can build a shelter rather than pitch a tent. Snow is a good insulator and cuts out all wind; inside a snow shelter it’s calm and quiet even when a blizzard rages outside. To build a proper one takes a few hours. Ice axes, cooking pans, and toilet trowels can all be used as digging tools, but a proper snow shovel speeds things up considerably.

  Whatever tool you use, digging snow is hot work, so it’s best to strip off your warm clothing so it doesn’t get soaked with sweat. There are various forms of snow shelters—caves, domes, trenches, and igloos. Which you build depends on the terrain. Caves can be dug into steep snow-banks. Start by digging a vertical slot a bit more than shoulder width that goes in at least 6 feet. Then dig out the area around the slot to form sleeping platforms with a lower area in the center that leads to the entrance to act as a sink for cold air. A curved, smooth roof will minimize drips. How big you make the cave depends on how many it must shelter, how much time you have, and how much snow there is. The entrance should slope downward out of the cave and be kept small to prevent snow and wind from blowing in. Make sure you include an air inlet to prevent carbon monoxide buildup when you’re cooking. It’s a good idea to mark the cave too. A ski pole poked through the roof does this and acts as a vent. Wiggle the pole every so often to keep the hole open.

  Using the IceBox to build an igloo.

  A snow trench is the quickest type of snow shelter to build.

  Where there are no steep banks, you can build a snow dome. Simply pile up a huge mound of snow, leave it a short while to harden, then dig out the center, leaving walls about a foot thick. Snow domes superficially resemble igloos, but igloos are much stronger and more complex and
require more skill and time to build. There is a tool that makes building igloos easy—the IceBox, a curved form into which you pack snow, and a long handle you use to determine the radius of the igloo and to ensure the snow blocks are positioned correctly. Using the form, you build a circle of snow blocks, each fitting next to the other, until the igloo is complete. The lightest IceBox weighs a touch over 5 pounds and can easily be strapped to a pack. With an IceBox, you can build an igloo in a couple of hours. If you’re going to set up a base camp in the snow, it could be worth carrying one.

  In a storm the quickest shelter to build is a snow trench. Mountaineers high in the Himalaya have survived for several days and nights in body-size “snow coffins.” A simple trench can be roofed with tilted snow blocks or with a fly sheet or tarp spread over skis or ski poles and the edges held down with snow. The aim is to get out of the storm as fast as possible. If heavy snow is falling, make sure the roof of your snow trench isn’t completely buried and that there is ventilation.

  SLEEPING BAGS

  Keeping warm at night is essential for enjoyable backpacking. Nothing destroys the pleasure of a trip like shivering through the night in an inadequate sleeping bag. Some people just pile on extra clothes at night, but I’ve never met anyone who does this by choice (a forced bivouac when you aren’t carrying a sleeping bag is another matter), and it sounds both uncomfortable and inefficient.

  A sleeping bag traps warm air, which keeps you from feeling cold. To prevent dampness from condensation, a bag must allow the moisture vapor given off by your body to escape, so both fill and shell should be breathable. If you intend to sleep under the stars, a bag with a quick-drying or even a waterproof-breathable shell is best. Even if it’s dry, dew or frost may dampen your bag. (For more information on insulation and how to keep warm, see pages 120–30.)

  Fill

  Choosing a sleeping bag is much easier than choosing a tent. There are far fewer designs, though there are many models. The biggest decision is the kind of insulation or fill, followed by how warm a bag you need. The ideal material would be lightweight but very warm, low in packed bulk, durable, non-absorbent, quick drying, warm when wet, and comfortable. Unfortunately, this ideal doesn’t yet exist, so compromises have to be made in terms of which properties are most important—determined in part by when and where you’ll camp and what shelter you’ll use. The basic choice is between synthetic fibers and waterfowl down.

  Synthetics

  Since the mid-1970s when DuPont launched Fiber-fill II, many synthetic fills have appeared; they all attempt to mimic down by being light and fluffy in order to trap warm air but low in bulk when compressed. There are two basic types of fiber. As you’d expect, short-staple fibers consist of short sections of fill while continuous filaments are endless strands of fiber. KoSa’s Polarguard is the best-known continuous-filament fill. There are well-regarded proprietary versions too, like Wiggy’s Lamilite. Polarguard comes in four types, of which 3D and Delta are the lightest and most efficient. Polarguard HV, 3D, and Delta are made from hollow polyester with a triangular cross section, which cuts down on weight and increases the insulation, since warm air can be trapped inside the fibers. Original Polarguard and Lamilite are solid polyester. Continuous filament is generally reckoned to be the most durable fiber. I’ve certainly found Polarguard tough in insulated jackets (see page 150). It’s comfortable, too.

  There are many versions of short-staple fibers, with new ones appearing frequently. The ones regarded as the best for sleeping bags are DuPont’s Thermolite Extreme and Thermolite Micro and Albany International’s Primaloft. Older fibers like Quallofil and Hollofil, both from DuPont, are less compressible and less durable and appear mainly in low-cost bags. Proprietary short-staple fills are mostly found in budget bags too. I’ve found Primaloft the most comfortable of the short-staple fibers. This microfiber is very soft and drapes around the body well. There are three types of Primaloft. Primaloft One is surprisingly water resistant, far more so than other synthetic fills, while Primaloft Two and Sport are similar to other synthetics in water resistance.

  Synthetic fills cost less than down, are easy to care for, and resist moisture. But they are not “warm when wet,” as some manufacturers claim—nothing is. What matters is how fast something dries, and synthetic fills dry fairly quickly, since they are virtually nonabsorbent. Because the fill doesn’t collapse when saturated, it retains much of its warm-air-trapping thickness, too. A wet synthetic-filled bag will start to feel warm in a comparatively short time compared with a wet down-filled bag, as long as it’s protected from rain and wind. You can’t sleep outside in a downpour in a synthetic-filled bag and stay warm, however.

  The disadvantages of synthetic fills compared with down are shorter life, less comfort over a wide temperature range, more packed bulk, and greater weight for the same warmth. The latest synthetics are lighter, more compressible, and more durable than earlier ones, but they still don’t compare with down. In the long run, down costs less too. One company that makes both down and synthetic bags estimates that with average use, a down bag will last at least twelve years (I have bags much older than this, as do many other people), but a synthetic bag will last only four years. Because down is expensive, awkward to handle, and needs to be kept dry, if a synthetic that performs as well ever does appear it will probably replace down. That day isn’t here yet, though.

  Down

  Down is the lightest, warmest, most comfortable and most durable sleeping bag fill. No synthetic yet comes near down for packability, low weight, and warmth. Down is the fluffy underplumage of ducks and geese and consists of thin filaments that trap air and thus provide insulation. Down recovers well from compression and goes on doing so for a long time, hence the good durability. Unlike feathers, in down there are no quills to poke through the fabric. A single piece of down is called a cluster and consists of a solid point, called a quill point, surrounded by a tangle of fine filaments. Large clusters with long tendrils fill more space and trap more air for less weight than small clusters. Large birds have large clusters, so down from geese is generally warmer than down from ducks. The more volume a given amount of down can fill, the higher its quality, because the thickness, known as loft, determines the warmth. Measuring the volume filled by an ounce of down determines the fill power. Down of 500 to 550 fill power (500 to 550 cubic inches of down per ounce) is the least expensive but provides less warmth for the weight than down with higher fill power. The warmest, lightest, and most expensive bags are filled with down of 750 to 900 fill power. Before being tested, down is stored for five days in a large screened box and regularly mixed and blown with a warm dryer. This “conditioning” stabilizes samples for consistent results. An ounce of the down is then placed in a measuring cylinder and a 68.4-gram weight is placed on the down. (One bag maker points out that the weight is more than twice the weight of the down and that this testing procedure ignores the fact that some bag manufacturers use extremely lightweight shells—such as DP Airnet and Pertex Quantum—and also that others unduly compress their super-high-fill down with overly beefy shells.) This process means the down is in just about perfect condition when measured. Even so, the results have a margin of error of plus or minus 5 percent. Western Mountaineering, from whose catalog I culled this information, calls the resulting fill power rating “optimistic” rather than “practical” and says that its fill power figures are the lowest its down would produce. In practice the figures can be taken as comparative rather than absolute. Down with higher fill power will be warmer for the weight than down with lower fill power, but it almost certainly won’t loft as much in the wilds as under laboratory conditions.

  People worry about down’s lack of insulation when soaked. Down can absorb a great deal of moisture, and it takes a long time to dry. Drying a sodden down bag outside in wet weather is practically impossible; it takes dry heat. But keeping down dry need not be difficult or a chore, and it’s harder to get down wet than many people think. I use down bags mos
t of the time, including in wet places, and I haven’t yet had one get more than a little damp. Packing a down bag in a waterproof stuff sack and sleeping in a tent or under a tarp when it rains are the best ways to keep it dry. It’s also wise to air down bags occasionally to remove any moisture picked up from humid air or from your body.

  If you want the warmth and comfort of down and the water resistance of synthetics, Marmot makes bags with down inside and Primaloft outside. The 30°F (−1°C) Fusion bag weighs 2 pounds, 4 ounces, and the 15°F (−9°C) weighs 3 pounds, 3 ounces. I’ve tried the 30°F; the rating is certainly accurate, and the bag is comfortable. The one problem I can see is that the down is likely to long outlast the synthetic fill. Using a light synthetic bag as a cover for a light down bag is probably a better idea.

  There’s currently no legal standard, but sleeping bags labeled as “down” should be at least 75 percent down, the rest being small feathers, which it’s impossible to totally separate from the down. Many bag makers use a higher percentage of down. The figures are often expressed in the form 85/15 or 85:15 for 85 percent down, 15 percent feathers. “Down-and-feather” fills should be at least 50 percent down, but “feather-and-down” fill is less than 50 percent down. Feather-and-down and all-feather fills have just about vanished, since they offer no advantages over synthetics, which are easier to care for. The more quills you feel in down fill, the higher the percentage of feathers.

  Down is a by-product of the food industry, and most down comes from places where waterfowl are eaten in large quantities, such as China and Eastern Europe.
