Cumulus Mysterious Traveller 500 sleeping bag relies on a proven design, a wider cut, more durable fabric (35 g/m²), and duck down with a fill power of 700 cuin. This series will appeal primarily to those looking for a reliable three-season sleeping bag with a great balance between weight, thermal comfort, and price.
What is the product suitable for?

The construction of the sleeping bag uses a more durable fabric Pertex® Quantum 35 g/m² (20-denier ripstop), which combines weight, durability, breathability, and packability well. The outer side of the fabric is treated with a permanent water-repellent DWR layer that will hold back light condensation or a few drops of water.
The sleeping bag is filled with 500 grams of duck down with a fill power of 700 cuin. The ratio of down to small feathers is 95/5. The upper chambers are separated from the lower ones and are filled with a slightly larger amount of down. The down is distributed here in a ratio of 55/45.
The sleeping bag uses trapezoidal chambers that prevent the formation of "cold spots" at the seams of two chambers. The Mysterious Traveller series is slightly more spacious. The width of the sleeping bag at the shoulders is 80 cm and 55 cm at the hips. Standard size M is suitable for individuals up to 190 cm tall.

For simple orientation, the tightening of the hood and collar is distinguished; you tighten the hood with a flat strap and the collar with an elastic band. The sleeping bag has a separate collar filled with down and secured with Velcro, which wraps around your neck on both sides and prevents heat loss through the hood. Inside the sleeping bag, there is a mesh pocket for your mobile phone, earplugs, or other small items.
The sleeping bag has a 175 cm long 5 mm YKK zipper with an enlarged slider to prevent it from getting caught in the fabric when zipping. At the feet, you will find a second slider, which is ideal for ventilation. Behind the zipper on the inner side, there is a down-filled insulating tube that minimizes heat loss through the zipper itself. Two Cumulus sleeping bags with opposing zippers (left + right) can be connected together.

A simple travel storage sack is included with the sleeping bag. The sleeping bag has a cylindrical shape with a volume of 6 liters and dimensions of 26/18 cm (height/diameter).
The original sack cannot be further compressed and is not waterproof, so we recommend getting a sack that that solves both problems. The ideal choice is STS compression sack eVENT Ultra-Sil of size S or a classic waterproof bag Sea To Summit Ultra-Sil Dry Sack about size 8 l.
You also get a large storage bag for home use with the sleeping bag, so the sleeping bag isn't unnecessarily compressed for a long time.
