Mountain Equipment Helium 400

Mountain Equipment Helium 400

Mountain Equipment's Helium Range is lighter than their Classic but lower priced than their Extreme range. Helium bags offer outstanding all round performance and are now lighter and warmer for their weight than ever before. The Helium 400 is ideally suited for Spring/Summer backpacking and cycle touring and will cope if the temperature becomes cooler.

The Helium 400 is constructed using slanted Box-Wall baffles throughout the entire main body, this increases the bags thermal efficiency and improves down migration control.The outer fabric is Helium 20D which is very compressible, durable and comfortable.

The Helium 400 features a single handed Lode Lock closure with quick release, this essentially is two internal captivated magnets which automatically pull together and then lock into place preventing the bag from accidentally opening during your nights sleep. The Gemini zip baffle system replaces bulky twin draft tubes used traditionally on cold weather bags by the baffle being incorporated in the sidewalls. This new construction is light, low bulk, efficient and protective. In addition, the bag also features an integrated and fully adjustable down filled neck collar. All these features contribute to retaining essential warmth whilst you are sleep.
