The best goose down on the market - 800+ fill

800 cuin goose down from Eastern Europe is the best down available on the market. It contains at least 90% down and each batch is individually tested to meet the 800 cuin fill and to meet all the conditions of the ethical DOWN CODEX®.

Goose feathers are gently cleaned with water without chemical treatment. This destroys the mites and the environment for their life, which is especially appreciated by allergy sufferers. The feathers retain their important fatness and loft, are packable well, have high insulation and low weight.

- 605 g of goose feathers.
- Minimum capacity of 800+ cuin.
- Down ratio 90:10
- Complies with DOWN CODEX®.
- Long life.

Construction details of the sleeping bag

In each chamber, the amount of feathers is precisely calculated per gram for minimum weight and maximum warmth. This innovative "chamber by chamber" approach was developed by Matt Fuller, who is the only outdoorsman to hold a PhD in feather research.
Structurally exceptional insulation - the so-called Body-mapping takes into account the needs of each part of the body separately. That's why Matt Fuller calculated the exact feather density in each chamber separately.
Not even a gram of heat escapes – Thanks to the alpha chambers, almost no heat escapes from the sleeping bag. Alpha chambers in the shape of trapezoids minimize heat loss through the seams and keep the feathers in place, without migration in the chambers. The heat remains inside thanks to the elimination of thermal bridges in the seams, as is known for example with classic H chambers.
3D hood without the need to pull it down - the hood is shaped to protect the head even without pulling it down. 7 chambers prevent feather migration, protect your head from heat loss and thus ensure a pleasant sleep. If you need to remove the hood, no problem. By the shape of the cord, you know exactly whether you are pulling the upper part of the hood (flat cord) or the lower part of the hood (round cord).
Ergonomic shape for the feet - the feet need to be insulated as best as possible, because they get little blood flow. The bottom of the sleeping bag is tapered in the shape of a trapezoid and the tip area is raised like a shark's fin. Thanks to this ergonomic shape, you will not press the chamber in the leg area with your feet and the insulating properties that keep your feet warm will not be lost. The bottom of the sleeping bag is made of the warmest V-chambers and is so complicated that it is made separately and then sewn to the sleeping bag.
The feathers used for the bottom of the sleeping bag and on the hood have a higher filling density, which prevents moisture from penetrating deeper into the chamber. You will appreciate this when sleeping in a grave, when in contact with a wet wall or when there is condensed moisture in a tent.
Protective 3D collar around the neck - to prevent heat from escaping from the sleeping bag, there is a down 3D collar on the inside that fills the space around the shoulders and neck. That's how the sleeping bag is "plugged". There is less feather density in the collar to precisely mold to the shape of your shoulders and neck. All the same, a magnetic stud that you can put on and take off intuitively with one hand.
Insulation pad under the zipper - the weakest point of sleeping bags is usually the zipper. The triangular bed is filled with feathers and synthetics, which adheres to the sleeping bag. The synthetics prevent the feathers from moving along the leg and at the same time insulates even when wet. The zipper is located in the lower half of the sleeping bag so that the heat that rises up does not escape through the zipper.
EXL stretch threads - they are used on the inside of the sleeping bag and "hug" you better. By eliminating air circulation in the sleeping bag, better insulation properties are achieved and thermal comfort is increased without adding weight.

YKK® zipper with automatic lock

In the Mountain Equipment sleeping bag, you will not experience the unpleasant feeling of waking up at night with the zipper open, because it has a zipper lock and will not unzip on its own. With a simple pull, you release the lock and open the sleeping bag only when you want to.

It works even after freezing - a high-quality zipper from the manufacturer YKK® is used for comfortable fastening without snagging. This particular zipper works without problems even in the cold and you can rely on it at any time.

DOWN CODEX® – a symbol of an ethical approach to animal husbandry

DOWN CODEX® is a control of the origin of feathers, its quality, ethical and ecological approach to animal husbandry. Every year, the farms from which Mountain Equipment buys feathers are inspected by the independent Swiss organization IDFL to meet the highest quality parameters. This guarantees a high quality of living conditions for the animals and thus also the quality of the feathers. One does not work without the other.

Each product with feathers has a unique code, under which you can find the origin of the feathers and its parameters.
A comprehensive and transparent system for auditing the origin of feathers, from all brands and anywhere in the world.
In Mountain Equipment products, feathers are always just a by-product of meat or egg farming.
