## Long description

The COCOON MummyLiner Flannel in African Rainbow is a premium sleeping bag liner specifically engineered for mummy-shaped sleeping bags. Crafted from high-quality, soft, brushed flannel, this liner offers significant thermal insulation, effectively increasing the temperature rating of your sleeping system while providing a cozy, skin-friendly surface. It serves as a protective barrier that keeps your sleeping bag clean, reducing the frequency of washing and extending the lifespan of your primary gear.
Advantages
The primary benefit of this flannel liner is its ability to add warmth to any sleeping bag, making it an excellent choice for cooler nights. The brushed fabric feels soft against the skin, offering superior comfort compared to standard synthetic linings. Its mummy-specific design ensures that there is no excess fabric, which helps in retaining body heat efficiently. Furthermore, the liner is lightweight and compact, making it easy to pack for any outdoor adventure without adding significant bulk to your backpack.
Suitable for
Camping and trekking in cool weather conditions
Travelers staying in hostels or mountain huts
Protecting sleeping bags from dirt and body oils
Adding extra warmth to existing sleeping bags
When it may not be suitable
This liner may not be the best choice for ultralight backpacking trips where every gram counts, as flannel is heavier and bulkier than silk or synthetic alternatives. It is also not recommended for use in hot, humid climates where the added insulation might cause overheating.
Key specifications
Material: 100% brushed flannel cotton
Shape: Mummy-specific cut
Function: Thermal insulation and hygiene protection
Compatibility: Fits most mummy-shaped sleeping bags
How to use
To use the liner, simply slide it inside your mummy-shaped sleeping bag before you go to sleep. Ensure the hood of the liner aligns with the hood of your sleeping bag for maximum coverage. When you wake up, you can easily remove the liner to air it out or wash it separately, keeping your main sleeping bag clean and fresh for the duration of your trip.
What to consider before purchase
Check the dimensions of your sleeping bag to ensure compatibility with the mummy cut
Consider the weight and pack size if you are space-constrained
Evaluate if the added warmth is necessary for your specific climate
Usage recommendations: To maintain the softness and integrity of the flannel fabric, machine wash the liner in cold water and air dry whenever possible. Avoid using harsh detergents to preserve the vibrant African Rainbow colors.
