Mountain EquipmentHelium 400 - Sleeping bag - Men's

The Helium 400 is a sleeping bag designed by the brand Mountain Equipment to offer you lightweight insulation from March to September. Although this sleeping bag is lightweight, it remains warm and insulating. Indeed, the Helium 400 is filled with duck down, providing excellent insulation. Additionally, the Helium fabric is dense, which offers a high level of wind resistance, thereby minimizing heat loss. Furthermore, the slanted box-wall baffles not only reduce the weight of the sleeping bag but also ensure an even distribution of the down within the sleeping bag for effective insulation. Finally, the Bulls Eye™ technology located at the foot box area is designed to limit the migration of down towards the bottom, always with a focus on lightness and compressibility.
