The Beginning of Down Insulation
Down insulation is a primary material used in outdoor gear like sleeping bags, jackets, and comforters. The roots of using down as an insulation material date back to the early 1900s. Humans have long understood the value of the natural thermal benefits of waterfowl feathers. Down insulation was initially used in sleeping bags during World War II, when soldiers needed protection from the cold.
What is Down Insulation?
Down insulation comes from the soft and fluffy under feather layer of waterfowl birds like geese and ducks. Down insulation is known for providing warmth without added weight, making it an ideal insulation material for outdoor gear. Down insulates by trapping small pockets of air: the more air trapped, the warmer and more comfortable you’ll be in cold weather.
Down Vs. Synthetics
While synthetic materials have become a popular alternative to down, it’s not unusual to see a top-grade down sleeping bag selling for twice as much as its synthetic counterpart in high-end camping gear shops. Synthetic materials like polyester and nylon and blends are cheaper to produce, but down insulation has a remarkable warmth to weight ratio and can last for many years with proper care.
Latest Innovations
The excellent thermal properties of down have lured researchers and scientists to work on new ways to make it even more effective. One innovation is the development of treated or hydrophobic down, which has added water-repellent properties.
This development has been made possible through the use of nanotechnology, which allows down feathers to be treated with a hydrophobic material that prevents water from seeping through the insulation and causing your gear to become wet.
The hydrophobic treatment increases the efficiency of the down insulation by 57 percent, making it more water-resistant and significantly better than untreated down insulation in damp conditions.
Another Innovation: Ethical and Sustainable Down Production
The ethics of using down as an insulation material have long been debated, with animal rights activists bringing to light that inhumane practices such as the live-plucking of birds for their feathers were commonplace in the industry. As a result, outdoor companies have started to look for ways to obtain down through ethical and sustainable production methods.
One example is a new certification program called the Responsible Down Standard (RDS), which mandates that outdoor companies only use down obtained from ducks and geese that have been treated humanely and have led healthy lives. Companies obtain certification by providing thorough documentation explaining where their down is sourced, what farming conditions the animal lives in, and how the bird is transformed into insulation material.
The Future of Down Insulation
Despite the proliferation of synthetic insulation and newer materials, down insulation remains incredibly popular for outdoor gear. The density and warmth of down continue to make it a go-to insulation material for cold and wet weather. Recently, companies have given more attention to the production of ethical and sustainable down and the further development of hydrophobic down.
Taking into account these latest innovations and developments, the use of down insulation in outdoor gear will continue to give travelers, campers, and hikers protection and warmth for years to come.
