To complete the tent standard walls are available, as well as walls with plain windows: with windows complete with mosquito net and shade, and walls with door.All walls can be secured to the roof by means of strong Velcro fasteners and with a similar system using a wide overlap at the legs; the walls can be fastened to one another to create a full and continuing side coverage.When using a single wall, this can be fixed to the legs with Velcro tapes, placed at different heights. All of the walls have loops to secure them to the ground, if necessary. At the base of the roof is a Velcro tape (50 mm) for rapid fastening to side walls. The walls are made in the same flame-retardant fabric as the roof. This fabric has passed the stringent USA CPAI-84/1995 test envisaged for tents.
