The opinion of Aventure Nordique

The Polish brand offers with its Core 400 sleeping bag, a model designed for a comfort temperature of 0°C, standard 13537. An ideal temperature range for summer hikes in the Alps. It is filled with 422g of 700 cuin duck down, with 95% down and 5% feathers repaired, all for a total weight of 747g.


It has a double-zip zipper that is protected by a cold-proof flap. Inside there is also a generous collar with drawstring and a pocket. The Core 400's hood is wrap-around and has a drawstring. Several suspension loops are located inside and outside the sleeping bag.


The main feature of the Core 400 is its Z-shaped partitioned construction. The walls are inclined between the different boxes trapping the down, allowing better insulation compared to a conventional H construction. The breathable fabric of the envelope is made of Duralight Shell, one of the lightest materials available.
