Frequently Asked Questions (FAQs)
What temperature rating should I choose for trekking?
Always choose a bag rated 10-15 degrees lower than the lowest temperature you expect to encounter. For example, if you expect 30°F nights, a 20°F bag like the Kelty Cosmic is a safer bet than a 30°F bag.
Is down better than synthetic insulation?
Down is generally lighter and more compressible, making it superior for trekking where pack space is limited. However, synthetic insulation performs better when wet and dries faster, though it is usually bulkier.
How do I store my down sleeping bag?
When not in use, store your sleeping bag in a large cotton storage sack or hang it up. Keeping it compressed in its stuff sack for long periods can damage the loft of the down and reduce its warmth.
Can I wash a down sleeping bag?
Yes, but you must use a specialized down detergent and a front-loading washer on a gentle cycle. It is crucial to dry it on low heat with tennis balls to break up clumps and restore the loft.
What is the difference between a mummy and a rectangular bag?
Mummy bags are tapered to fit the body closely, which maximizes heat retention and minimizes weight. Rectangular bags offer more room to move but are heavier and less efficient at trapping body heat.
