Should I choose a down or synthetic sleeping bag?

Blog - How to choose a sleeping bag

The right choice depends on how you camp.
Down is lighter and warmer for its weight.
Synthetic is better in wet conditions and usually cheaper.

Which sleeping bag is best for hiking?
Down sleeping bags are best for hiking because they’re lighter and pack smaller, making them easier to carry long distances.

Which sleeping bag is better in wet weather?
Synthetic sleeping bags are better in wet conditions because they still insulate when damp. Wet down doesn’t.

Is a heavier sleeping bag warmer?
Generally, yes. A heavier sleeping bag is usually warmer, regardless of whether it’s down or synthetic.

Are synthetic sleeping bags better value?
Yes. If you’re driving to camp and not carrying it far, synthetic sleeping bags usually give better warmth for the price.

Which sleeping bag is easier to look after?
Synthetic sleeping bags are easier to clean and maintain. Down needs more care.

Quick answers
Hiking and light packs: Down
Car camping or wet weather: Synthetic
Easy care and better value: Synthetic
