Mammut's sleeping bag systems and accessories are developed with Norwegian technology – Ajungilak - a wholly owned subsidiary of Mammut Switzerland.

All sleeping bags are filled with either first class 650+ cuin goose down or technologically advanced MTI filling and offer greatest comfort to different environments.

The meaning of Ajungilak in Norwegian refers to ''Sleep Well'' and this has been the underlining concept and theme for Mammut/Ajungilak sleeping bag systems
