Frequently Asked questions

What size compression sack is best for a sleeping bag?

This depends on how compressible the insulation is and how light the fabrics are. Rough guide: summer down bag 10 L | 3-season down bag 13 L | 3-season synthetic bag 13-20 L | 4-season down bag 20 L | 4-season synthetic bag 30 L. Cold-weather use: if in doubt, size up.

Are compression sacks waterproof?

If the model name includes the term 'dry', it is waterproof. Compression sacks without the word 'dry' in the name are only water resistant.

How do I clean / store a compression sack?

Hand wash a compression sack / compression dry bag (rather than machine washing) - use a mild soap and rinse thoroughly. Do not dry in a dryer. Store in a cool, well-ventilated dry place.
