Incazelo Yomkhiqizo

Izikulufo zokuzibhoboza zokufulela ziyizikulufu eziklanywe ngokukhethekile ezivame ukusetshenziselwa izinhlelo zokufulela. Lezi zikulufu zenziwe ngephuzu elicijile elizivumela ukuthi zibhoboze izinto zokufulela njengensimbi, ipulasitiki, noma ukhuni ngaphandle kwesidingo sembobo ebhojwe ngaphambili. Izikulufu zifaka ikhanda le-hex noma ikhanda lewasha elihlinzeka ngoxhumano oluvikelekile phakathi kwezinto zokufulela kanye nedekhi yophahla.

Izikulufu zokuzibhoboza zodwa ngokuvamile zenziwe ngensimbi engagqwali noma insimbi, ezinikeza ukumelana okuphezulu nokugqwala nokugqwala. Izikulufu ziza ngosayizi nobude obuhlukene, futhi zenzelwe ukumelana nezimo zezulu ezinzima lapho uphahla luchayeka khona.

Esinye sezici eziyingqayizivele zezikulufu zokuzibhoboza yikhono lazo lokudala isivalo esibamba amanzi eduze kwembobo yesikulufu. Lokhu kufezwa ngerabha noma iwasha ye-neoprene efakwe ngaphansi kwekhanda eliyisikulufu, elivala imbobo futhi livimbele amanzi ukuthi angangeni.
