Consider before choosing
The -9C and -1C listings are not identical warmth configurations. Verify comfort rating and mat insulation rather than treating the title as a comfort guarantee.

Sleeping bags buying advice
Before you buy
Fit affects the night
Check body-length guidance, shoulder room, hood and zip side. Compare the same size when checking weight or price.
Include your mat
Your mat, shelter, clothing, moisture and individual cold sensitivity all influence the sleep system. A bag rating is not a weather guarantee.
From first use to the next trip
Use, care & repair
01Try the complete system
Test the bag with your usual mat and clothing before a remote trip. Check the zip, hood and available space without compressing insulation.
02Keep insulation dry
Protect it from rain and air it when conditions allow. Follow the care label for washing and drying; down and synthetic products can have different instructions.
03Store without compression
Once completely dry, follow the manufacturer's storage guidance. Keep the transport sack separate from long-term storage where a larger storage bag is specified.

Common buying questions
Good to know
Which temperature rating should I compare?
Start with the published comfort rating on a consistent test basis. Check whether the number in the product title is instead a limit rating and whether the size or version changes the specification.
Does a higher fill power automatically mean a warmer bag?
No. Fill quantity, construction, fit and the published temperature test also matter. Fill power alone is not a complete warmth comparison.
Can I use the same washing instructions for every sleeping bag?
No. Use the care label and the exact manufacturer's instructions. They take precedence over general washing advice.
Keep your options open
