• Filled with high-quality European hypoallergenic goose down with a fill power of 850 cuin and RDS certification
• On the outside the ultralight, waterproof and perfectly breathable CRAFTEVO® 2.5L laminate (100% recycled nylon, PU membrane, 2.5L construction) with water-repellent DWR treatment (C0).

• Ergonomically shaped foot section for comfort and warmth of your feet.
• Straight zip construction for smoother operation, lower weight and even better thermal insulation properties of the sleeping bag. Below the entire zip is a quilted insulation panel filled with down that effectively prevents heat loss.
• "Z" baffle construction that ensures sufficient insulation thickness at every position.
• The hem around the anatomically shaped hood is filled with CLO Vivo Endurance synthetic insulation, which reduces heat loss, is more resistant to exhaled moisture and prevents drawstring pressure.
• The semi-automatic, waterproof SHZ zip with two sliders reaching to the ankles has a thickness of 3 mm instead of the classic 6 mm, reducing heat loss and overall weight.
• Advanced draft collar construction prevents heat loss. Unique closure of the collar around the shoulders in a "shell shape" without snaps or Velcro; simply close the zip and pull the cord.
• A storage bag made of brushed polyester is included.
• The included compression bag reduces the volume of the sleeping bag by up to 13 times.
• Inner 20 x 12 cm pocket for items you want to have to hand or protect from frost (phone, batteries, medicine, etc.).
• Self-locking, one-hand adjustment of the inner collar around the shoulders and the opening around the face.
• The ergonomically shaped hood allows head movement, both lying down and sitting, and guarantees effective insulation.
• Loops for hanging the sleeping bag (e.g. for drying or storage).
• The anatomical shape of the sleeping bag follows the body shape, with the lower section narrowed precisely so that you can still reach your feet when closed (e.g. to take off socks), but at the same time the insulation performance is not limited by an excessively wide cut.
• Zip on the left side (ideal for right-handers).

An extremely lightweight fabric has been used in the mummy sleeping bag : Toray™ Airtastic™ with DWR (C0) treatment (100% recycled nylon) and CRAFTEVO 2.5L (100% nylon, PU membrane). This fabric offers exceptional breathability while providing good tear and water resistance.

Comfort temperature -5°C

For these sleeping bags, the comfort temperature has been tested in an independent laboratory following 2017 European standard ISO 23537-1. This temperature represents the lower limit at which the user is in thermal equilibrium, neither feeling cold yet warm (determined by a healthy woman under normal conditions of use.

Temperature limit -10°C

The limit temperature represents the lower limit of thermal comfort at which the user's body is in thermal equilibrium (the person is neither cold nor too hot). Determined for a healthy man and standard user conditions.

Extreme temperature -28°C

The lower limit at which there is a risk of health damage due to hypothermia. The sleeping bag should not be selected for this, this serves as an informative indicator of danger. The sleeping bag will have to be used above this temperature.
