Frequently Asked questions
What's the difference between a synthetic and down sleeping bag?
Synthetic Sleeping Bags: still insulates when wet. Up-front cost is lower, but heavier and bulkier and have a shorter lifespan.
Down Sleeping Bags: not ideal in very wet environments. Higher up-front cost, but lighter, packs smaller and lasts much longer.
Can you sleep on your side in mummy sleeping bag?
The cut of mummy sleeping bags varies between brands - some are really tight. Sea to Summit Spark & Flame fit snugly but still allow side sleeping. Ascent, Altitude, Trek, Journey, Traverse and Venture sleeping bags have a broader mummy cut that is perfect for side sleepers.
Is this sleeping bag machine washable?
Do not wash a sleeping bag in a top-loader washing machine - a front-loader with a wool or silk program is OK. Use down soap (supermarket detergent residue sticks insulation fibers together). Dry the bag in a dryer (cool or warm) with a couple of clean tennis balls.
How do I care for/ store my sleeping bag?
Make sure your sleeping bag is completely dry before storing (in a cool, dry place) in a bag or pouch that will allow the bag to loft up. Pro tip - use a liner to reduce frequency of washing.
How to pack a sleeping bag in a backpack?
Pack bulkier sleeping bags in a compression sack (compression dry bag for wet environments). Pack compact sleeping bags in an eVac Dry Bag. Pro-tip: always have your sleeping bag inside your pack at the bottom: mounted externally, they can snag on branches.
