About Columbia Sportswear
Founded in 1938, Columbia Sportswear Company has grown from a small family-owned hat distributor to one of the world's largest outerwear brands and the leading seller of skiwear in the United States. Columbia's extensive product line includes a wide variety of outerwear, sportswear, rugged footwear and accessories. Columbia specializes in developing innovative products that are functional yet stylish and offer great value. Eighty-year-old matriarch Gert Boyle, Chairman of the Board, and her son, Tim Boyle, President and CEO, lead the company. Columbia's history starts with Gert's parents, Paul and Marie Lamfrom, when they fled Germany in 1937. They bought a small hat distributorship in Portland, Oregon, and named it Columbia Hat Company, after the river bordering the city. Soon frustrated by poor deliveries from suppliers, the Lamfroms decided to start manufacturing products themselves. In 1948, Gert married college sweetheart Neal Boyle, who joined the family business and later took the helm of the growing company. When Neal suddenly died of a heart attack in 1970, Gert enlisted help from Tim, then a college senior. After that it wasn't long before business really started to take off. Columbia was one of the first companies to make jackets from waterproof/breathable fabric. They introduced the breakthrough technology called the Columbia Interchange System, in which a shell and liner combine for multiple wearing options. In the early 1980s, then 60 year-old Gert began her role as "Mother Boyle" in Columbia's successful and popular advertising campaign. In 1998 the company went public, and moved into a new era as a world leader in the active outdoor apparel industry. Today, Columbia Sportswear employs more than 1,800 people around the world and distributes and sells products in more than 50 countries and to more than 12,000 retailers internationally.

Sleep Well: Finding the Right Sleeping Bag
Sleeping bag technology has come a long way from the days of cowboy bedrolls. These days, there are a number of high-tech materials and designs available to keep you warm during the coldest outings. Here's a short list of things to keep in mind when you're shopping for a bag: Buy for Cold
It's a safe bet that on at least one of your adventures, the nighttime temperature will drop unexpectedly. That's why it's smart to buy a bag that's rated for the lowest possible temperature you expect to face on your camping and backpacking trips. For summer trips, a bag rated at +35 degrees or higher will likely do the trick. If you like to camp in higher elevations in the summer, or if spring and fall outings are in your future, consider bags rated from +10 to +35. Winter adventurers should look for bags in the -10 to +10 range, while those on serious winter alpine climbs and expeditions will want a bag rated lower than -10. Keep in mind that sleeping bag manufacturers' temperature ratings only estimate the minimum temperature at which the bag will provide warmth. Take these numbers with a grain of salt, as different folks generate different amounts of heat when they sleep. If you're the type who likes to pile on the covers even on warmer nights, go for a bag that's rated ten degrees colder. The opposite is true for "warm" sleepers--a 35-degree bag will probably work for you on a 25-degree night. Goose or No Goose?
The most important component of any sleeping bag is its insulating material. Modern sleeping bags offer two choices: goose down or synthetic. While both materials have advantages and disadvantages, down bags are considered superior because of their phenomenal warmth-to-weight and warmth-to-bulk ratios. While providing great insulation, down is extremely compressible and light. There's a reason why geese can fly and stay warm through the winter! Down also boasts great long-term durability and will typically retain its insulating properties after years of use. All of that said, there are many high-quality synthetic bags on the market and synthetic materials are getting better all the time. While a synthetic bag will weigh somewhat more than a down bag at an equivalent temperature rating, synthetic bags perform better when wet. (Yes, the Achilles heel of down is that it loses all insulating properties when wet.) If your trips take you to wet climates, you may want to consider a synthetic bag for this reason alone. Keep in mind, too, that many people are allergic to down--synthetic bags are non-allergenic. Finally, down is considerably more expensive than synthetic, which might tip the balance for adventurers on a budget. Bags for All Shapes
Sleeping bags come in two basic shapes that reflect their intended use. Mummy-shaped bags offer the best warmth because they conform to the body's contours. This minimizes the amount of body heat the body must put out to maintain a constant temperature. Many mummy bags are offered in women-specific shapes and sizes, as well. Rectangular bags, while they do offer more room to toss and turn, are less thermally efficient because they contain more open air space. Also, they are typically heavier than mummy bags, and are generally not offered with down insulation, making them best suited for car camping or short backpacking trips. Pad Yourself
No matter what kind of bag you choose, a sleeping pad is a required accessory. Not only do they provide much-needed comfort when sleeping on the ground, pads also offer crucial warmth for your backside, as the weight of your body compresses--and renders virtually useless--the sleeping bag insulation that lies beneath you. |
