The tent is double-layered and consists of an inner tent and an outer layer – the rain fly. The inner tent has a trapezoidal floor plan with an entrance on its longest side. The outer tent has a large vestibule that can be entered through two different entrances.

Tent concept

It is based on the principle that the rod structure is strung in tunnels made of perforated material outside the rain fly. The rain fly and the inner tent (which is suspended under the rain fly) are built simultaneously after the tent poles are threaded through the tunnels. The advantage of this method is that the inner tent can be detached from the rain fly, and the rain fly can then be erected separately, resulting in a single-shell tent without a floor.


It is located at the top of the dome of the rain fly. The canopies of the ventilation windows are shaped so that they are not tilted by the wind. This prevents leakage even during rain with strong wind.

Building a tent

We push the tent poles of the structure through the perforated tunnels outside the rain fly and insert the steel spikes strung on the floor near the rain flyinto the tubes at the end of the tent poles. We fasten the inner tent to the loops on the inside of the rain fly. We anchor the erected tent with pegs and cords and fasten it with plastic clips.
