Frequently Asked Questions

Q: How do I choose the right filling weight for my environment?

Choose based on the comfort temperature: 400g fill is ideal for 1~11°C, while the 1000g fill is designed for extreme cold reaching -14°C to -4°C.

Q: Is this sleeping bag truly machine washable?

Yes, the bag is designed to be machine washable. We recommend using a gentle cycle and specialized down detergent to maintain the loft of the white goose down.

Q: What makes the 400T 20D nylon shell superior?

The 400T density provides a tighter weave that is both highly waterproof and tear-resistant, offering better protection against wind and rain compared to standard nylon.

Q: Can the sleeping bags be spliced together?

Yes, our design allows for splicing, enabling two bags to be connected to create a larger double sleeping bag for couples or friends.

Q: Do you offer custom branding for bulk textile orders?

Absolutely. We specialize in customizable outdoor gear, allowing you to personalize the design, colors, and logos to fit your brand identity.

Q: How does the mummy shape improve warmth?

The mummy shape contours closely to the body, reducing the amount of empty air space that needs to be heated, thereby maximizing thermal efficiency.
