Sleeping Bag FAQs:

1.What is a synthetic sleeping bag?

Synthetic insulation used in a traditional sleeping bag is typically made of polyester fibers, which can be made from recycled materials like PET plastic bottles.

Synthetic insulation is quick-drying and provides warmth even if wet (something feather down insulation has a hard time doing).

2. What are the benefits of synthetic insulation?

Synthetic insulation tends to be more affordable than down insulation, in addition to being durable, hypoallergenic, lightweight and water resistant.

3. Does a synthetic bag lose its warmth?

All sleeping bags lose their warmth over time. However, a synthetic bag retains its temperature rating for an average of 7 years, while a down sleeping bag retains warmth for an average of 10 years.  Synthetic insulation offers benefits like water resistance and affordability, but will lose warmth faster under increased compression. The life of a sleeping bag will vary depending on how often you use it and how you keep it while not in use.

4. How do you care for synthetic sustainable sleeping bags?

When not in use, let your sleeping bag air out as much as possible and allow it to dry completely before storing it. It should be stored in a cool, dry location away from direct sunlight. Do not store your synthetic sleeping bag uncompressed – it should always be compressed and placed back in its stuff sack. 

Avoid cleaning your sleeping bag unless absolutely necessary. Small stains and spillages can typically be wiped up with a moist soapy cloth. Zippers should be cleaned and lubricated on a regular basis.
