The Helium 600 is a sleeping bag designed by the brand Mountain Equipment to offer you lightweight insulation from spring to autumn. Although this sleeping bag is lightweight, it remains warm and insulating. Indeed, the Helium 600 is filled with duck down, providing excellent insulation. Moreover, the Helium fabric is dense, giving you a high level of wind resistance and therefore minimal heat loss. Additionally, the slanted box-wall baffles not only reduce the weight of the sleeping bag but also distribute the down evenly for effective insulation. Finally, the Bulls Eye™ technology located at the footbox aims to limit the migration of down towards the bottom, always with a focus on lightness and compressibility.
