Marmot - Helium Long - Dunsovsäck

Top thermal performance thanks to first-class materials

It provides incredible warmth: the Helium Long down sleeping bag from Marmot! It doesn't matter whether you’ll be in the Western Alps or trekking somewhere else in the world, the Helium Long will keep you toasty and dry no matter where you are. The lightweight sleeping bag features a bulky goose down fill with a fill power of 800+ cuin that's located in slightly curved baffles, so it’ll be able to optimally distribute and regulate the insulation. Plus, the Helium Long offers taller individuals more space than any other mummy sleeping bags in the same weight class.

Clever details for versatile function

The Helium is equipped with a double water-repellent treatment on the down and outer shell to ensure you can spend comfortable nights in your tent or whilst bivouacking outdoors. Some other great features include the anatomical wrap-around foot box and the Nautilus hood with a special baffle construction to keep your head toasty even when it’s cold and damp!
