Isitulo Sokuphumla I-YO ilandela imigaqo-siseko ye-ergonomic yokuhlala ngokulula kunye nemigca yejiyometri ecocekileyo eyenza ukuba unobumba u "YO". Kwenza umahluko phakathi kwento enkulu eyenziwe ngamaplanga “eyindoda” kunye nelaphu eliqinisekileyo, eliyi- “fem” elihleliyo kwesihlalo kunye nomva, elenziwe nge-100% izinto ezihlaziyiweyo. Ukuxinana kwendwangu kufezekiswa ngokudityaniswa kweefayile (ebizwa ngokuba yi "corset"). Isitulo sokuphumla sidityaniswa nesitulo esiba yitafile esecaleni xa ijikeleze ama-90 °. Uluhlu lokukhethwa kwemibala lubavumela bobabini ukuba bangene ngokulula phakathi kwezitayile ezahlukeneyo.
Igama leprojekthi : YO, Igama labayili : Rok Avsec, Igama lomthengi : ROPOT.
Lo mklamo wombono ongamangalisayo ngumnqobi wembasa yesilivere kwiphulo loyilo lwefenitshala. Ngokuqinisekileyo kufuneka ubukele ingqokelela yoyilo lwabayili abaphumelele ibhaso lesilivere, ukuze ufumanise imisebenzi emininzi emitsha, eyilelwe ngokutsha, eyoqobo nenobuchule yoyilo lwefenitshala.
