Aura X 450/800

The X 450/800 from Aura is a sleeping bag that stands out due to its shape and design. It has been designed specifically for climbing and mountaineering, for bivouacs in difficult conditions. Its anatomically adjusted shape is the result of a design that takes up as little space as possible in the bivouac, of a search for comfort both lying down and sitting up, without losing insulation. To achieve this, it has side panels on the torso area that increase thermal insulation.

It is filled with 450 grams of Polish goose down, 800 cuin. The down is divided into H-shaped compartments to limit heat loss. Its half-zip front allows for freedom of movement, for example to eat while staying warm. By being shorter, it limits heat loss. Equipped with a double slider, it allows you to take a lanyard outside to stay safe during the night.

The hood and legs are made on the outside with a Toray Delfy fabric. A two-layer membrane that offers a waterproof level of 10,000 mm water column and a breathability of 10,000 H²O/m². The torso is made of a Pertex Quantum outer fabric. This is an ultra-light, durable (ripstop) and water-repellent (DWR) fabric. The interior is made of Pertex Polygiene, a soft touch fabric coated with silver ions, which have antibacterial properties and prevent odour formation.
