Care & Maintenance Instructions

To keep your sleeping bag performing like new for years to come, follow these simple care tips:
  1. Spot Cleaning: Use a damp cloth with mild soap to clean small dirt patches rather than washing the full bag.
  2. Machine Washing: Wash on a gentle, cold-water cycle using a front-loading washing machine. Do not use bleach or fabric softeners.
  3. Drying: Air dry by laying it flat out of direct sunlight, or tumble dry on the lowest possible heat setting with clean tennis balls to fluff up the microfiber filling.
  4. Storage: Ensure the bag is completely dry before rolling it tightly into the compression sack to prevent mildew formation.

Frequently Asked Questions

Is this sleeping bag noisy or crinkly when you move around?
Not at all. While the outer shell is water-resistant nylon, the inner lining uses a premium soft-touch polyester brush layer that is quiet, smooth, and comfortable against your skin.

Can two of these bags be zipped together to make a double size?
Yes. You can easily unzip two of these rectangular bags completely and connect them to create a massive, cozy double-sized sleeping layout for two people.

Is it easy for a child to pack back into the carrying sack?
Absolutely. The foldable design and wide-mouth compression sack make it highly manageable for kids, boys, and girls to roll up and store away without frustration.
