When bikepacking, solo hiking or mountain passes, every gram and centimeter counts, and at the same time, you need to have maximum confidence in your equipment. The XENITH II LONG sleeping bag can offer you all of this. Thanks to the highest quality 900 cuin fill power down, weighing only 517 g, it is windproof, durable, and moreover, with a 10-year warranty. Ultra-light summer sleeping bag for high mountains.



In the Mountain Equipment XENITH II LONG sleeping bag with PLASMA material and goose down, you will be comfortably warm down to 1 °C. The weight of 510 g and very good packability are optimal for summer mountain passes, solo hiking, and other adventures in the summer mountains, where you need to get the weight down to a real minimum!
