ROCK FRONT 400 Ultralight Long  - is a warm down sleeping bag with a cocoon design specially designed for winter hiking and mountain climbing.
The ROCK FRONT 800 3D L Long sleeping bag is designed for stocky people up to 197 cm tall.
It has an improved hood and collar fixing system, the collar is looser and wraps around the neck from all sides.
The long zip allows you to easily regulate the temperature inside, which adds comfort during winter hiking and mountain climbing, it is possible to partially open the zip at the bottom or top to release excess heat.
In a tourist shelter, it is convenient to use it as a blanket, and the sleeping bag can also be used as an underquilt for a hammock (with the Rock Front Underquilt Set - not included).
3D technology is a differential cut, where the outside of the sleeping bag is larger than the inside. Thanks to this design, tension is generated exclusively on the inner fabric of the sleeping bag, always leaving free space for down insulation. This ensures stable and even heat retention even during active sleeping movements.
Two insulated strips securely fix each other along the zip and prevent cold air from penetrating.
You can connect 2 sleeping bags together (any ROCK FRONT models with a YKK № 5 zip) and get a large 2-3 person sleeping bag.
The sleeping bag has an anatomical design with additional space for the legs (footballs) to rest in a natural position.
The filler is high-quality natural goose down Fill Power 800 with hydrophobic impregnation, thanks to which the sleeping bag will remain dry for a long time even in high humidity conditions.
Material - thin and durable nylon with hydrophobic impregnation, resistant to fluff, fibres and wind.
Includes a compression pouch for transport and a mesh storage bag.

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.
