Down Doubles

There are several advantages to spending the money on a down sleeping bag. Down is extremely lightweight and yet extremely warm. It compacts easily, and so it's the choice for most backpackers.

However, there is another advantage to down that can keep you cozy all year long. Many campers use their down sleeping bag as a comforter when they aren't camping. Just as you zip two bags together to form a double sleeping bag, you can unzip your sleeping bag and use it as a comforter.

Unzipped, a large sleeping bag will cover most beds, which means your down sleeping bag can be even more useful. In winter, they keep you warmer, and in summer, they breathe and can keep you cooler.
