ROCK FRONT 400 Ultralight M Long is a universal down sleeping bag with a cocoon design for mountaineers and hikers in cold weather.
The ROCK FRONT Ultralight M LONG is an extended version of the ROCK FRONT Ultralight sleeping bag, designed for people up to 188 cm tall.
A convenient central zip with two sliders allows you to open the bottom of the sleeping bag for ventilation, or turn the sleeping bag into a large blanket.
With the help of loops along the zip, the sleeping bag can be attached to a quilted mat to get more internal space.
2 ROCK FRONT Ultralight M Long sleeping bags can be connected to each other to create a double sleeping bag.
The sleeping bag has an anatomical design with extra space for the legs (footballs) to rest in a natural position.
The filling is high-quality natural goose down Fill Power 870+ (confirmed by the IDFL laboratory in Switzerland) with hydrophobic impregnation, which ensures that the sleeping bag stays dry for a long time even in high humidity conditions.
The material is a thin and durable nylon with hydrophobic impregnation, resistant to fluff, fibres and wind, and its stability and abrasion resistance are achieved thanks to the thin Micro Rip-stop structure.
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.
