Product description

Even though the mid-latitude winters are getting more and more milder on average you're usually still better off picking a down sleeping bag for mountain touring and staying in high-elevation regions in particular. The Helium by Marmot is one of them - and does a great job at that! It has the classic mummy shape and is lined with goose down according to the EU standard. The chambers are arranged in such a way, that the down is distributed evenly and stays in its place almost all the time. A special DWR treatment ensures improved water-repellent properties. The trapezoidal foot area is designed in such a way that you still have enough space to turn around and that the warmth insulation is improved at the same time. Getting into it is child's play due to the second zip which also provides addition ventilation when it gets a little too warm at night. With the Marmot Helium sleeping bag you'll be as protected as it gets!
