of the outer shell 20 the supports 22 or any other part of the helmet cover 10 can be easily identified against the exterior shell of the helmet h further the helmet cover 10 can be impregnated with a dark color such as black to help indicate when a high impact has been received causing the abs thermoplastic to stress whiten at the point of impact the stress whitening such as the stress whitening area 62 shown in fig6 can be more pronounced against a dark pigmented helmet cover thus the helmet cover of the present invention can mark an area of impact by a stress fracture 60 stress whiten areas 62 or polymer particles 64 being released from the polymeric material of the helmet cover 10 the helmet cover 10 of the present invention serves to disperse forces of an impact load realized on the helmet cover 10 such that when the impact load realized on the helmet cover 10 exceeds a threshold impact load the helmet cover 10 can indicate the specific location on the helmet cover 10 where the impact load was realized the impact load indicators can be in the form of physical fractures 60 fig6 disposed on the outer shell 20 or particles 64 released due to the fracture or a mark on the helmet cover caused by stress whitening 64 these load indicators or marker mechanisms allow the wearer of the.
