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 sleeping bags fit snugly but still allow side sleeping. Ascent, Trek, 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.
