Mountain Equipment Glacier 450 Regular sleeping bag, obsidian

Mountain Equipment Glacier 450 Regular sleeping bag

Quality sleep is one of the basic requirements for full regeneration during any outdoor activity. The Mountain Equipment GLACIER 450 LONG down sleeping bag has an upper material resistant to water and wind and is still very breathable. The sleeping bag is filled with duck feathers and, together with the elaborate construction, will allow you to sleep comfortably even at -9 °C.
 

DRILITE® LOFT

DRILITE® LOFT 30 D is a strong and light (55 g/m2) waterproof surface material with a PU coating, which makes a great bivouac sleeping bag. It also has a water-repellent DWR treatment on the surface, which contributes even more to keeping the feathers dry even in wet conditions. The feathers are thus protected from getting wet and thus also from losing their heat-insulating properties. Thanks to its water resistance and low weight, the feathers maintain a high loft for maximum thermal insulation in any conditions.

The SUPERSOFTTM 30 inner material is chosen for its low weight (49 g/m2), high breathability, exceptional durability and pleasant feeling to the touch. It is also a feather-proof material.
 

Quality duck feathers with 700+ fill

Very high-quality duck feathers from China contain at least 90% down, their filling is at least 700 cuin and meets the ethical DOWN CODEX®. The feathers are gently cleaned with water without chemical treatment. This destroys mites and the environment for their life, which will be appreciated by allergy sufferers. The feathers retain their important fatness and loft, are easily packable, have high insulation and low weight.
 

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 with 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 combination of alpha chambers and beveled chambers, the sleeping bag is characterized by excellent thermal insulation. Alpha chambers in the shape of trapezoids and beveled chambers minimize heat loss through the seams and keep the feathers in place, without migration in the chambers. Heat stays in the sleeping bag thanks to the elimination of thermal bridges in the seams through which heat escapes.
• 3D hood without the need to pull it down - the hood is shaped to protect the head even without pulling it down. 5 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.

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. ​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.
