A shell for ballistic helmet formed from a plurality of paraaramide fabric layers such as KEVLAR-KM2(R), and bonding resin. All fabric layers have areal density less than 200 g/m2, preferably part of them have areal density less than 160 g/m2. The number of paraaramide layers is greater than 28, preferably 38 and more. The bonding resin constitutes less than 12% of the shell weight. The shell has average thickness less than 6.5 mm and average areal density less than 7.5 Kg/m2. A method for the production of such shells includes pressing and bonding the plurality of layers at pressure equal to or above 150 Kg/cm2, preferably above 300 Kg/cm2.
