Abstract: A ventilated cooling and protective garment including a hood portion (31) with a facial opening (14) surrounded by a facial peripheral ring (13) and a complete or partial body portion (32, 33), and a facial shield (10) comprising a transparent shield (11) and a facial peripheral connector (12) supporting and air-tightly attaching the transparent shield (11) to the facial peripheral ring (13) around the facial opening (14), wherein the facial peripheral ring (13) is pulled against the head of the user by the facial shield support (20) and include spacers (13a, 13b) to provide a permeable close non-air-tight fitting between the facial peripheral ring (13) and the head of the used, and an air inlet (A1) is included in the complete or partial body portion (32, 33) and at least a portion of an air outlet (A2) is included in the facial shield (11), or vice versa.

Abstract: A multi-layered material that includes a layer of natural leather or collagen leather with holes and/or micro-holes and coated with a hydrophobic agent, which is superimposed and adhered, by means of hydrolysis-resistant adhesives, said adhesives being arranged in a non-laminar fashion, to a layer of waterproof, breathable material to prevent the passage of water and to allow the passage of air therethrough.

Abstract: A protective liner, attachable to the inner surface of a helmet, comprising an inner face and an outer face oriented towards the inner surface of the helmet, wherein the joining of faces gives rise to a plurality of inflatable chambers permeable to water vapour and connected by means of pressurised air distribution channels. The chambers and channels form a single body extending at least along the inner surface of the helmet above the Frankfurt plane. The outer face comprises a layer of rigid material while the inner face comprises a layer of elastic material, whose area expands when the chambers are filled with air, such that the expansion in volume occurs mainly by means of the deformation of the elastic layer.

Abstract: A waterproof, breathable bag that defines an interior space completely surrounded by waterproof material, at least part of said waterproof material also being a breathable multi-layered material that includes a layer of waterproof, breathable material to prevent the passage of water and to allow the passage of air therethrough; wherein the waterproof, breathable bag includes in its interior a heating device that includes a heating resistor in thermal contact with the inside air of the bag, a battery also housed in said bag and connected to a heating resistor and a controller device.
