4.0 BAR / bivouac tent

4.0 BAR
4.0 BAR

„4.0 BAR“ is a bivouac-tent which combines the ease of a bivy-bag with the comfort of a one person tent. In stead of bars, air beams create the space that allows you to spend the night in the wilderness.
The activation of the integrated pump rolls out the tent and builts it up. At the same time, the air inflates the sleeping mat, which is the ground sheet of the tent and describes a separate air cell. The inflated structure ensures stability through defined kinks, which tense the shelter. The created overhanging walls guarantee optimum utilization of the floor space.
