CUMULUS was established in 1989, immediately following the transformation of the Polish political structure. It was founded by Zdzislaw Wylężek, a Gdynia mountaineering enthusiast and former employee of the co-operative organization “Sail”, a state tourist equipment manufacturer, operating during the previous political era. From the beginning, CUMULUS focused on clothing and down sleeping bags and had already established cooperation with the company Perseverance Mills, the producer of the excellent Pertex fabric (the brand later sold to the Japanese Mitsui), which they still use today.
