Aimed at serious trekkers and cycle tourers the Helium 800 is a lightweight packable sleeping bag for multi-day travels. The Helium Range from Mountain Equipment is unashamedly aimed at outdoor enthusiasts who like to travel fast and light and are looking for high levels of performance with a reduction in weight. The recycled Helium™ 20 fabric is exceptionally light but strong, durable and packed with 90/10 Pure Duck Down with a 700+ fill power. As with all Mountain Equipment down sleeping bags the Helium 800 comes with an anatomically designed hood and foot-box and these along with the slanted box-wall baffles ensure the bag works efficiently. So if you are serious about your trekking and touring and head out in colder conditions the Mountain Equipment Helium 800 Sleeping Bag would be a great choice.
