Recommendations for use
- The sleeping bag is designed to be used with a sleeping pad - a camping mat that insulates the body from the cold ground.
- Fold the sleeping bag into the transport bag randomly each time - this will prevent the insulation from falling off and extend its service life.
- It is recommended that you wash your sleeping bag as little as possible, following the manufacturer's recommendations and using appropriate detergents, and using a liner will help you wash your sleeping bag less often.
- It is recommended to dry the sleeping bag whenever possible in the field, and be sure to dry and ventilate it well before storing it for a long time.
- Store the sleeping bag in the most fluffy, non-compressed state - this will extend the service life of the insulation, and it is even better to store the sleeping bag in a special mesh bag.
