The opinion of Aventure Nordique

The Rect 500 from Polish brand Cumulus is a duck down sleeping bag. Without a hood and rectangular in shape, it offers plenty of space and comfort and is suitable for a wide range of uses. It can be used as a duvet or sleeping bag. Its L-shaped zip also allows you to slip inside with your feet sticking out.


The 500 grams of RDS 700 cuin Polish duck down filling provides good insulation and compresses easily. The comfort temperature is 4° Celsius. The Rect 500 has 14 H-shaped compartments. There are no seams between the top and bottom, allowing the down to be distributed where it is most needed. When it gets colder, you can tighten the elastic at the neck.


The 5 mm YKK zip with double slider forms an L shape around the sleeping bag, making it easy to open at the foot end to create a draught. An insulated flap provides protection when temperatures drop. Opening the zip completely creates a rectangular duvet measuring 200 x 160 centimetres. The products in the Rect series can be joined together to create a large sleeping space for two.


The zip is only on the left side. If you would like the zip on the right side, simply turn the sleeping bag inside out.


Compact when stored, the Rect can be easily carried in a rucksack. It is suitable for a variety of uses and is ideal for camping, cycle touring, van life or, more generally, for anyone looking for space to sleep.

Points to remember

A sleeping bag that converts into a duvet with duck down insulation. For use when camping, in a van, bivouacking, cycle touring, or if you want more space than a sarcophagus-shaped duvet provides. Comfort temperature: 4°C, 910 grams.
