Holding device for protection face-mask for connecting it with protection helmet Holding device for protection face-mask, which is fixed at protection helmet, has fitting hooks connected with flexible length-adjusted belts. Hooks are made for introduction into receiving recesses made onto protection helmet. Rest, working with friction and geometrical closing, in combination with flexibility of constriction belt, which serves simultaneously for individual adjustment of mask when it is put onto face, prevent automatic opening of hook. Slide members matched with rests for shift provide automatic optimal balancing of constriction belts. Connection between constriction belt and adjusting hook is made by means of cast holder formed on constriction belt, which is held for geometrical closing in recess, connected with adjusting hook of clamp member. |

Protective headwear has enclosure 26 provided with inwardly facing surface which faces user's head, and outwardly facing surface which faces away from user's head 10. Outer layer 28 is superposed the top of at least portion of outwardly facing enclosure 26. Breakable means 30 is adapted for fixed attachment of outer layer 28 to remaining part of headwear in one or more places. Breakable means 30 is configured so that it is broken when force exceeding threshold value is applied to outer surface 28 of headwear, said force acting at least partly tangentially so as to turn headwear and user's head. Upon destruction of breakable means 30 m in one or more places, the applied force urges at least part of outer layer 28, which accepted said force, to move relative to enclosure 26 similarly to protective motion of human's scalp relative to skull. |

Face net has isolating cover for head and neck, said cover preventing insects from penetration therethrough. Face net is also equipped with spreader layer made in the form of system consisting of spaced apart spreaders adapted for equally spacing of isolating cover from user's head and neck by distance inaccessible for insect's sting or proboscis. Isolating cover is positioned opposite face. Face net is provided with spacing device adapted for spacing of isolating cover from user's face and made in the form of shield positioned on user's forehead and fastened on user's head by means of ring. |

Transformable cap has crown and peak separable from one another by means of zipper-fastener. Ornamental cord is positioned onto zipper fastener at site where crown is joined to peak, said ornamental cord being attached with its ends to peak and used to serve as handle for bag, which is produced from peak separated from crown, or as means for attachment of peak to user's head when peak is used as headwear. Cap may be transformed to four articles: cap, bag, purse, and headwear formed as peak of cap. |
