Nothing provides peace of mind during a trip into the backcountry like knowing that you have a warm sleeping bag to crawl into when the sun dips. That way, no matter what frigid temperatures come your way, you’ll be toasty and able to sleep through the night.A down sleeping bag provides the ultimate degree of warmth for backpackers andmountaineers. Whether you’re in need of a lightweight three-season bag for fair weather adventures or a heavy-duty sleeping bag you can take to the world’s coldest mountain ranges, addnature.co.uk has a down sleeping bag for you.
Why Choose Down?
Ask any experienced backpacker or mountaineer whether a down or syntheticsleeping bag is the better choice, and they’ll point you towards a down bag every time. That’s because down has the best warmth to weight ratio of any insulating material. In practical terms, that means a sleeping bag insulated with down willhold in more of your body heat and weigh less than a comparable synthetic bag.On top of that, down sleeping bags are more compressible so you save valuablespace in your backpack. They also retain their loft for many years of use, which somewhat negates the price difference between down sleeping bags and less durable synthetic sleeping bags over the long term.The only real downside to down sleeping bags is that down loses its warmth once it gets wet, and it can be hard to dry out in the backcountry. Always store your down sleeping bag in a waterproof stuff sack to ensure it stays dry during your trip.
Choosing the Right Down Sleeping Bag
Season & Temperature Ratings
The first thing to decide when choosing a down sleeping bag is what conditionsyou plan to use it in. If you only backpack during the summer, a summer sleeping bag rated for temperatures above 4°C will be plenty warm. On the other hand, winter conditions in the mountains may require a sleeping bag with enough insulation to provide warmth down to -30°C. The majority of down sleeping bags fall somewhere in between and are rated for three-season use.When thinking about temperature ratings, it’s important to recognize that they are typically optimistic. A bag rated for -5°C won’t let you freeze at that temperature,but you’ll be cold enough that you probably won’t sleep. As a good rule of thumb,the lowest temperature at which a sleeping bag will be comfortable is about 3°C higher than the rated temperature.
Mummy vs. Rectangular Sleeping Bags
The shape of your down sleeping bag also makes a big difference to how warm it will be.Rectangular or envelope-shaped sleeping bags offer a lot of space, which makesthem as comfortable as a blanket. However, all that air space means you need to put out a lot of body heat to warm up the bag. Worse, the wide openings at the top of these bags allow a lot of warm air to escape. As a result, rectangular bags are typically rated for summer or warm three-season use.Mummy sleeping bags, on the other hand, leave less air space around your body, which typically helps keep you better insulated. These sleeping bags also feature a hood that cinch tightly down over your head to prevent heat from escaping out of the top of the bag. The downside is that mummy sleeping bags don’t offer muchroom to move around, which can make it difficult for some people to sleep.
