Weight
Are you looking for a winter down sleeping bag that won't take up half your backpack and won’t weigh you down? With the new Cumulus Teneqa series, you can't go wrong. Thanks to high-quality materials and a well-designed construction, they have a perfect ratio of thermal comfort to weight. The 850 model is perfect for those who set out on winter hikes even in colder temperatures.

The manufacturer has opted for the proven Pertex Quantum fabric weighing 29 g/m², which perfectly combines low weight, durability, breathability, and packability. On the outer side, the fabric is treated with a durable water-repellent (DWR) coating that will hold back light condensation or a few drops of water.
The sleeping bag is filled with 850 grams of goose down with a fill power of 850 cuin. The down to small feathers ratio is 95/5. The upper chambers are separated from the lower ones and are filled with slightly more down. The down is distributed here in a ratio of 55/45.

The chambers of the sleeping bag have a V-shaped construction. It is one of the most advanced types of chambers, minimizing the formation of so-called cold spots at the seam between the chambers. At the same time, it has a relatively low weight.
In order for the down to achieve sufficient loft, the sleeping bag is slightly wider than most three-season models. The width of the sleeping bag at the shoulders is 85 cm and at the hips is 59 cm. Based on our experience, the basic size M is suitable for individuals with a maximum height of 190 cm.
The foot box construction, named Shark-fin, prevents down compression, is comfortable, and provides better thermal performance than conventional constructions.

For simple orientation, the tightening of the hood and collar is distinguished: the hood is tightened with a flat strap, and the collar with an elastic band. The sleeping bag has a comfortable collar filled with down, which will wrap around your neck from both sides and prevent heat loss through the hood. The sleeping bag features two elongated baffles on each side, designed to better distribute the down within the bag and enhance thermal comfort. Inside the sleeping bag, there is a mesh pocket for a mobile phone, earplugs, or other small items.
The sleeping bag features a 175 cm long YKK zipper with an extended pull to prevent it from snagging on the fabric when closing. At the feet, you will find a second puller that is ideal for ventilation. Behind the zipper on the inside, there are two down-filled insulating tube, which minimize heat loss through the zipper itself. Two Cumulus sleeping bags with opposite zippers (left + right) can be connected together.

A simple travel storage sack is included with the sleeping bag. The sleeping bag is packed in it into a cylindrical shape with a volume of 11,1 liters and dimensions of 32/21 cm (height/diameter).
The original sack cannot be further compressed and is not waterproof, so we recommend getting a sack that addresses both issues. An ideal choice is STS compression bag eVENT Ultra-Sil of size M or classic waterproof bag Sea To Summit Ultra-Sil Dry Sack about size 13 l. You also get a large storage sack for home with the sleeping bag so that it doesn't get unnecessarily compressed for a long time.
