ROCK FRONT 1000 3D Ultralight L Long is the warmest down sleeping bag in the ROCK FRONT range, specially designed for winter hiking and mountain climbing.
The ROCK FRONT 1000 3D Ultralight L Long sleeping bag is designed for stocky people up to 197 cm tall.
It has an improved hood and collar fixation, the collar is looser and wraps around the neck from all sides.
The zip is shortened to knee level for better heat retention, and it is also possible to partially open the zip at the bottom to release excess heat.
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.
Along the zip is a system of two insulated strips that reliably protects against blowing.
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, thanks to which the sleeping bag will remain 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, its stability and abrasion resistance are achieved thanks to the thin Micro Rip-stop structure.
It comes with a compression pouch for transport and a mesh storage bag.
Rock Front 1000 3D Ultralight L Long: for hiking and mountain climbing, mountaineering.

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.
