Seeking Shelter
CLIMATE CONTROL Four-season tents are built for people who camp in severe weather conditions like monsoon rains, high winds and snow. Three-season tents are built for the rest of us. Their shapes are designed less for snow and wind, and more for comfort and usable interior space. Even in the three-season category, though, you want to look for the features that suit your particular camping weather conditions. Camping in the Northwest requires first-class protection from the rain while camping in the South puts a premium on ventilation. In some areas a rainfly must be deployed for the occasional thunderstorm. Camping in the deserts of the Southwest is all about shade during the day, but temperatures can really drop at night. Ultraviolet (UV)-resistant fabrics are also important; tent fabrics that are not UV resistant can degrade after just a few seasons of use. SIZE The third major consideration when purchasing a tent is the number and sizes of people in your party. Fewer people: smaller tent. MATERIAL AND CONSTRUCTION Most tent poles are made of steel, fiberglass or aluminum. Manufacturers are constantly seeking a balance between weight, strength and affordability. Much of the cost differences in tents can be found in the type of poles used. “Aluminum is stronger and lighter than fiberglass, but more expensive,” says Curt Dinges, product manager of Cabela’s Camping Division. Fiberglass tends to be lighter, more flexible and more expensive than steel. Some tents are sold with your choice of aluminum or fiberglass frames. The fiberglass version will be a little heavier, but less expensive. The material a tent is made from is also a big factor. Most high-quality tents use polyesters and nylons. “Nylon starts out stronger,” according to Dinges, “but over the course of time there’s a point at which exposure to the sun, UV rays and rain weakens nylon. In the long run, polyesters can be better than nylon.” This is especially true for rainflys. “Polyester is a desired fly fabric due to its low stretch when wet,” according to Andrew Day, Kelty Tent product manager. “Also, polyester resists UV damage more so than nylon. On the other hand, nylon resists abrasions better than polyester. That is why a heavier weight nylon is commonly used as a floor fabric.” The weight of a fabric is rated by denier (d). This d number is how much 9000 linear meters of yarn or filament weighs in grams. Higher denier means heavier fabric, which generally means better quality. Ripstop fabrics are also desirable for their durability. COATINGS Tent fabrics are not waterproof by themselves. They must be coated to make them waterproof — usually with polyurethane. Tent coatings are tested and rated by how much water pressure they can withstand before water droplets form inside. Kelty’s Day said, “waterproof tests are determined by placing water in a cylinder with one end sealed by the fabric being tested. The height of the water in millimeters before leaking is noticed determines the water resistance of the material. Most waterproof tent materials are in the 1000 to 2000 mm range.” Tom Gooch, senior camping designer for Johnson Outdoors (Eureka! tents) says 800 mm is probably the minimum you want on a fly, “but something like 1200 mm is preferable.” Higher coating numbers are better. Thicker coatings are more durable and less likely to develop leaks due to abrasions. But it’s not just the thickness of the coating, according to Chuck Smith, president of Wenzel. “You want to make sure you get a double-pass (two coatings); one on the inside and one on the outside.” Perhaps more than any other factor, quality materials and construction will increase the life expectancy of your tent.
