Product details: Mountain Equipment Helium 400 - Long Down Sleeping Bag Majolica Blue

Mountain Equipment Helium is a down sleeping bag from the award-winning Helium series. All models in this series are characterised by their amazingly light weight in relation to their thermal performance. At the same time, they impress with the usual high Mountain Equipment comfort and a special alpine fit.

While the Helium TM 20 outer material is very light, highly breathable and windproof, the SupersoftTM 30 inner material is equally light and soft. The thermal collar with Lode LockTM technology is also extremely comfortable and durable. This outstanding construction is rounded off by an efficient and ingenious chamber system with optimised distribution of the duck down. These achieve a fill power of at least 700 cuin. This also means the best duck down quality in the world, while the 90/10 filling contributes significantly to optimum thermal performance.

The Helium sleeping bag is also ideal for the environmentally conscious. The Down Codex introduced by Mountain Equipment ensures maximum environmental and animal protection. The down used in production comes exclusively from animals kept in a species-appropriate manner, whose comparatively long life expectancy guarantees the highest level of down quality.
