The invention relates to a controllable ribbed thermoinsulative chamber of continually adjustable thickness, which is used to pneumatically determine its thermal conductivity. The invention describes the manned of constructing such a chamber and the manner of controlling it. The abovementioned chamber is used in designing articles of clothing with a self -regulating thermal insulation. One or more chambers are used in the construction, together with adequate devices for controlling and monitoring the workings of thermoinsulative chambers. Special attention is paid to the construction of forced ventilation of the garments designed in the above way. The garments designed in the above way are suitable for police usage, maintenance services, watchmen services, security of the open objects and premises, workers in cold storages, athletes like mountain climbers, alpinists, sailing boaters and the like, wherever the temperature of the environment is radically changed in the course of usage.
