Izinketho kanye nezitayela zezikhwama zokukhwela izintaba zangaphandle:
Ama-backpacks angaphandle abelokhu egxile kakhulu kubathandi bangaphandle ngenxa yezici zawo ezihlukile, inqubo yokukhiqiza kanye nokukhethwa kwezinto ezibonakalayo. Ngokwezinhlobo ezahlukene zemidlalo yangaphandle, abathengi babeke phambili izidingo eziphakeme kakhulu zobungcweti kanye nokusebenza kwama-backpacks ezemidlalo angaphandle. Iningi lama-backpacks ezemidlalo angaphandle akhona asebenzisa izindlela zokuguqulwa kanye nokwelashwa okungangeni manzi okuhlanganisiwe kwezindwangu ezisetshenzisiwe, kanye nokuthunga, ukucubungula i-lamination yangaphandle, njll., ngokuklama iziteshi zokujikeleza komoya engxenyeni yomzimba we-backpack, ukusetha izingidi zephasiwedi, imichilo ekhanyayo, kanye nama-alamu. Dala ama-bock pockets kanye namanethi ephaketheni phezulu, emzimbeni, phansi kanye nezikhwama zokulala ukuze uthuthukise ukungangeni manzi, ukuphefumula, ukuphepha, ukulayisha kanye neminye imisebenzi evamile ye-backpack, kanye nokunakekelwa kwempilo, ukuthwala okulungisekayo, kanye nesikhungo sokulinganisela amandla adonsela phansi kanye neminye imisebenzi emisha. Vele, ngokuthuthukiswa kwesayensi nobuchwepheshe, ukwanda kwabasebenzisi, kanye nokuhlola okujulile kwezidingo zomsebenzisi, ama-backpacks ezemidlalo nawo athuthukise izinhlobo zokuklama ezihlukile kakhulu.

Izikhwama zokuthwala izintaba zihlukaniswe ngezigaba ezimbili: esinye isikhwama esikhulu sezinyawo esinomthamo wamalitha angu-50-80; esinye isikhwama esincane sezinyawo esinomthamo wamalitha angu-20-35, esaziwa nangokuthi “isikhwama sokuhlasela”. Izikhwama ezinkulu zokuthwala izintaba zisetshenziswa kakhulu ukuthutha izinto zokuthwala izintaba ekukhuphukeni izintaba, kuyilapho izikhwama ezincane zokuthwala izintaba zivame ukusetshenziselwa ukukhuphuka izintaba eziphakeme noma iziqongo zokuhlasela. Izikhwama zokuthwala izintaba zenzelwe ukubhekana nezimo ezibucayi. Zenziwe ngendlela emangalisayo futhi zihlukile. Ngokuvamile, umzimba mncane futhi mude, kanti ingemuva lesikhwama lenzelwe ngokwendlela yemvelo yomzimba womuntu, ukuze umzimba wesikhwama usondele ngemuva komuntu, ukuze kuncishiswe ingcindezi emahlombe ngezintambo. Lezi zikhwama azinamanzi futhi ngeke zivuze ngisho nasemvuleni enkulu.
