The thick draft tube backing the zipper provides excellent heat retention. The anti-snag stiffener ensures smooth operation of the zipper.

The expedition side baffels offer extra warmth and warmth distribution through the sleeping bag.

The double ended zipper has reinforced sewing to increase strength in sensitive areas.

The puffy draft collar prevents heat loss for cozy next to body warmth.

Designed to cradle the feet in uncompressed insulation, this unique footbox eliminates cold spots. Internal baffles form a multi-faceted array of down chambers for extremely efficient heat conservation in this critical area.

The Expedition hood is designed to preserve every joule of warmth.

The different shaped cord ends on the hood closure cord allow the user to easily feel and adjust the hood closure.

The Ultra XP is only certified to Limit -28°C due to a limitation in the certification, however the sleeping bag is designed and tested to be used in -40°C.

The expedition inner pocket has extra space to keep electronics warm overnight.

The sewn in loops allows the sleeping bag to be attached to the mattress, or hung up to air out.

The large zipper garage keeps the zipper head away from the face.

Product Description

The Ultra XP is the warmest sleeping bag in the entire Ultra series. It was developed specifically for expedition use and is reliably warm even in extremely cold temperatures. Countless down chambers ensure even heat distribution and excellent thermal performance.

To meet the demands in such extreme temperatures, the Ultra XP is cut extra wide. The 3D foot box with 11 individually filled down chambers ensures toasty feet. A thick, adjustable draft collar retains warmth within the sleeping bag. Additionally, a double zipper flap keeps the cold out. The expedition hood provides efficient insulation around the head and the large interior pocket keeps you organized.

The shell fabric is recycled, PFC-free and protects against moisture. Only RDS certified down is used as filling. Despite all these clever features, the Ultra XP is lightweight considering its thermal performance, making it the perfect companion for expedition mountaineers, extreme winter bivouacers or a journey to polar regions.

It's an open secret that the EN thermal test only works reliably down to about -15°C - -20°C.
That is why we only state a temperature recommendation for our beefy expedition sleeping bag that has been tested in real world conditions. Factors such as your physical constitution, the sleeping mat and tent used as well as the prevailing weather conditions play a major role in the bags performance, and these cannot be reflected in test results. -40° C can be regarded as the extreme temperature rating for the bag.

The EN (European Standard) rating is a standardized test that aims to set measurable targets and standardize temperature claims for sleeping bags. It is designed to help the consumer make an informed decision by using independently derived temperature values. Each EN sleeping bag test has four temperature ratings: Upper Limit, Comfort, Lower Limit, and Extreme. The three most common ratings are the following temperature ranges: Comfort, (Lower) Limit, and Extreme.

For these measurements, it is assumed that a “standard man” is 25 years old, 1.73 m tall, and weighs 73 kg; a “standard woman” is 25 years old, 1.60 m tall, and weighs 60 kg.

Comfort: the temperature at which an average woman can expect to sleep comfortably in a relaxed position.
Limit: the temperature at which an average man can sleep comfortably for eight hours without waking up.
Extreme: the minimum temperature at which an average woman can tolerate severe cold exposure for six hours. There is a risk of damage to health (no danger of death from hypothermia, but frostbite is theoretically possible).

Most companies advertise the Limit rating for men's sleeping bags and the Comfort rating for women's.

It is best to store the sleeping bag in the mesh storage bag provided. This will ensure that the insulation retains its maximum bulk and thermal performance. When traveling, it is okay to compress the sleeping bag and carry it in the included stuff sack.

When you return from a trip, it is very important to let your sleeping bag dry completely. Then store it in the mesh storage bag in a dry and temperature controlled place.

If you wash your sleeping bag too often, the insulation can suffer (down or synthetic). The insulating power may decrease. We recommend cleaning the sleeping bag with a damp sponge. If the sleeping bag needs a more thorough cleaning, use only a front-loading machine (no agitator!) and a special detergent from Nikwax or McNett.

Before you put the bag in the washing machine, close the zipper. Use a cold water and gentle wash cycle, and after the wash cycle is complete, run a second rinse cycle without detergent. This will ensure that all detergent residue is removed. Two spin cycles will help get a lot of moisture out of the sleeping bag.

It is best to hang the sleeping bag afterwards and air dry it. Keep massaging the sleeping bag the down tufts apart. Depending on the humidity, it may take several days to dry completely. If you need to dry it faster, use a tumble dryer on low heat (often there are special down drying programs). To loosen up the down in the dryer, you can put some tennis balls in the dryer with it.
