Iyo jekete rehupenyu rakajeka rakagadzirwa zvakanakisa, uye zvakare zviri pachena mumvura. Zvakanakira vanotsvaga kuti vawane anofona pasi pechiedza chekutsvaga. Kushandiswa kwemhando yepamusoro yekudhivha, iyo yemukati foam musimboti inogona kuchengetedza bhachi rehupenyu rinoputika mumvura, uye jira rekunze repolyester rinogona kubatwa zvakanaka, iro rinogona kunyatso dzivirira mvura , Izvo zvakasiyana neyakajairwa jekete rehupenyu zvinhu. Unhu hwakanaka kwazvo, bhanhire rinogona kugadziriswa zvakasununguka maererano nemuviri wemupfeki, uye rinotamirwa kumunhu akaripfeka pachake. Zvekutamba kunze mumvura, kukwira pamusoro pemvura, kuredza kunze kana zvichidikanwa, uye kuunza bhachi rehupenyu. Kushandisa zvinhu zvakatipoteredza, zvakachengeteka kushandisa. Vese vakuru uye saizi yemwana inogona kugadzirwa kuti isangane nezvido zvako.

Iro jekete rehupenyu rine mvura yakanaka, haipindiki, iri nyore kuisa uye kubvisa, haikanganisi mabasa emuviri evanhu, uye inogona zvechokwadi kuve nechokwadi chekuchengetedzwa kwevanhu vari mumvura. Mauto edu ane bhachi rehupenyu revest. Iyo isingapindi mvura iri pamusoro ndeye tepi ine mativi maviri yakagadzirwa nerabha yakakosha. Kune masaga mana anoyangarara akazadzwa nekapok kumberi nekumashure. Huremu hwese hunongova 1.5 kg, asi hunogona kubereka zvinopfuura 16 kg yeBuoyancy, murwi ane zvombo zvakakwana anopfeka uye anoyangarara pamusoro pegungwa, pamusoro pemvura haingapfuuri mafudzi. Kunyangwe bhachi rehupenyu rakabvaruka, pachine zvakawanda zvebuoyancy.

Pamusoro pekugadzira hukuru hukuru, bhachi rehupenyu remutyairi weNaval Air Force zvakare rine zvimiro zvekuzivikanwa zviri nyore uye kuramba shark. Rudzi urwu rwejaketi rehupenyu zvakare kazhinji vest mhando. Kuwedzera pamasaga mana akayangarara akazadzwa nekapok pachipfuva chayo, panewo pombi inofuridza pachikamu chakabudikira chesaga rinoyangarara. kunze kugungwa.
Upenyu bhachi, iro rinozivikanwa sevest life, imhando yezvipfeko zvinoponesa upenyu, zvakagadzirirwa sevheti, yakagadzirwa nejira renylon kana neoprene (NEOPRENE), buoyancy material kana inflatable material, reflective material, etc. Hupenyu hwese hwebasa ndeye 5. -7 makore, uye ndeimwe yemidziyo inoponesa upenyu pazvikepe uye ndege. Kazhinji vest mhando, yakagadzirwa nefuro plastiki kana koki. Iine buoyancy yakakwana yekupfeka pamuviri, kuitira kuti musoro wemunhu ari kunyura ugone kubuda mumvura.
