The opinion of Aventure Nordique

The Core 550 from the Polish brand Pajak is a sleeping bag suitable for trekking. Lightweight, it weighs only 885g in Regular size, but it does not overlook the filling. It has 565g of 700 cuin duck down, with 95% down and 5% feathers repaired. It offers a comfort temperature of -3°C, standard 13537.


It is carefully designed and manufactured with quality materials. The breathable Duralight Shell envelope is extremely lightweight. The Z-shaped partitioned construction, with the inclined walls between the chambers, provides better insulation than a conventional H-shaped construction.


The Le Core 550 sleeping bag has an enveloping hood with a drawstring and a generous collar. The zipper is protected along its entire length by a cold-proof flap. Located on the left side, it is equipped with two zips.
