Jekete lowala la moyo lapangidwa bwino kwambiri, ndipo limawonekeranso m'madzi. Ndikosavuta kwa ofufuza kupeza woyimba pansi pa kuwala kofufuzira. Kugwiritsa ntchito zipangizo zapamwamba zodumphira m'madzi, mkati mwa thovu lamkati kumatha kusunga jekete lopulumutsa moyo m'madzi, ndipo nsalu yakunja ya polyester imatha kukhudzidwa bwino, yomwe imatha kuletsa madzi kulowa, zomwe ndizosiyana ndi zipangizo wamba za jekete lopulumutsa moyo. Ubwino wake ndi wabwino kwambiri, lamba limatha kusinthidwa momasuka malinga ndi thupi la wovalayo, ndikusamutsira ku mkhalidwe wabwino wa wovalayo. Kuti musewere panja m'madzi, kukwera pamadzi, kusodza panja ngati kuli kofunikira, ndikubweretsa jekete lopulumutsa moyo. Kugwiritsa ntchito zipangizo zoteteza chilengedwe, ndikotetezeka kugwiritsa ntchito. Kukula kwa akuluakulu ndi ana kumatha kusinthidwa kuti kukwaniritse zosowa zanu.

Jekete la moyo lili ndi mphamvu yotha kulowa m'madzi, sililowa madzi, ndi losavuta kuvala ndi kuvula, silikhudza zochita za anthu, ndipo lingathe kutsimikizira chitetezo cha anthu omwe ali m'madzi. Gulu lathu lankhondo lili ndi jekete la moyo lofanana ndi jekete. Chosalowa madzi pamwamba pake ndi tepi yokhala ndi mbali ziwiri yopangidwa ndi mphira wapadera. Pali matumba anayi oyandama odzazidwa ndi kapok kutsogolo ndi kumbuyo. Kulemera konse ndi 1.5 kg yokha, koma imatha kupanga mphamvu yoposa 16 kg, msilikali wokhala ndi zida zonse amavala ndikuyandama panyanja, pamwamba pa madzi sipadzapitirira mapewa.
