Frequently Asked Questions

Q: What is the best way to clean a duck down sleeping bag?

We recommend using a mild detergent specifically for down products and a front-loading machine. Always air dry or tumble dry on low heat with tennis balls to restore the loft of the down.

Q: Is this sleeping bag suitable for extreme winter expeditions?

This bag is rated for temperatures as low as -5°C. While excellent for 4-season camping and general winter use, for extreme arctic conditions, we suggest pairing it with a thermal liner.

Q: Can I customize the size or materials for bulk orders?

Yes, we specialize in manufacturing customized home and outdoor textiles. We can adjust the dimensions, outer shell materials, and fill weight based on your specific requirements.

Q: How does the mummy shape benefit the user compared to rectangular bags?

The mummy shape contours to the body, significantly reducing the amount of cold air trapped inside and making it much more efficient at retaining body heat.

Q: Does the water-resistant shell protect against heavy rain?

The shell is designed to be water-resistant, meaning it handles light rain, dew, and damp ground. For heavy rain, we always recommend using the bag inside a tent or with a waterproof bivy sack.

Q: What information is needed to get an accurate shipping quote?

To provide an accurate shipping cost, please provide your full delivery address, the total number of pieces, and any specific packaging requirements you may have.
