Umumaro w'Ibanze: Ibuye ry'Ikirago Gikoreshwa mu Buryo Butandukanye Gikiza Ubuzima Umwandiko w'Igitabo: Shadow ni ikirago gikiza ubuzima gikoreshwa mu buryo butandukanye, cyagenewe gufasha abantu bahunze intambara, ibihe by'ikirere biteye impungenge n'ibindi bibazo byihutirwa. Shadow ihuza imikoreshereze itatu: uburyo bwo koga (buoyancy aid), ikirago gishyuha, n'agakiraro koroshye ko kuryamamo. Ikireziga cy'ifoma riri imbere mu gikoresho gitanga imbaraga zigera kuri 90 newtons zo koga mu mazi, naho urutare rwo mu mbere rurinda inyandiko z'ingenzi kutabuzana amazi. Ubwoya bw'aluminium buri imbere busubiza ubushyuhe bw'umubiri, bugatuma umuntu akomeza gushyuha. Uburyo bwo gushyira hamwe hakoreshejwe ubushyuhe bukabije (high-frequency heat sealing) butuma igikoresho gikomera kandi kitinjira amazi. Impine z'urutare rwiyongoyoye (elastic bands) zituma igikoresho gipfundikwa vuba mu gutwara no gukingurwa vuba iyo bikenewe.
