Wengi wa uzito ni hiyo kuchukuliwa mbali mabega, kupunguza uwezekano wa kuumia kutokana na bega kamba shinikizo (backpacks wengi vifaa tu na straps bega inaweza kuathiri mkao wa mtu amebeba zaidi ya kilo 14 (30 lbs)), pamoja na kuwa isiyokuwa ya juu ya mwili mbalimbali ya mwendo. backpacks nyingi zina uwezo wa kuwa imefungwa na ama utaratibu buckle, zipper, au kavu-mfuko aina kufungwa ingawa kutumia mifano michache drawstring zimefungwa lock kamba kwa compartment kuu.

Wengi wa mzigo katika bodypack unafanywa na nyonga. bora mzigo wa kubeba mfumo haipaswi kuvuruga wearer asili mkao, usawa na maneuverability. mzigo lazima kutawanywa kwenye muundo wa skeletal katika hata namna, na haipaswi kuzalisha vikosi unbalanced juu ya mwili.

frameless

rahisi backpack kubuni ni mfuko zinatokana na seti ya mgongo. Packs vile ni kutumika kwa ajili ya usafiri wa jumla wa bidhaa, na kuwa na uwezo kutofautiana. miundo rahisi na wajumbe wa mfuko moja kuu. Hii inaweza kuwa pamoja na utando au cordage straps, wakati mifano ya kisasa zaidi kuongeza mifuko ya ziada, straps kiuno, straps kifua, padded bega straps, migongo padded, na vifaa wakati mwingine kutafakari kwa ajili ya usalama aliongeza wakati wa usiku.

usalama wa baadhi ya miundo ya backpacks hawa wamekuwa kukosoa na Uingereza NHS, wengi mfuko miundo kuwa aliona "salama" kwa ajili ya watoto.

Packs sura ya nje

External Packs sura walikuwa iliyoundwa na kubeba mizigo mizito (> kilo 20 au 40 lb), kutoa msaada wearer zaidi na ulinzi na bora uzito usambazaji kuliko, frameless amefungiwa mfuko rahisi. Mbao pakiti muafaka zilitumika kwa karne duniani kote. Ötzi Iceman inaweza wametumia moja katika Copper Umri Alpine Italia,[2][3] ingawa baadhi archaeologists kuamini sura kupatikana kwa mwili ilikuwa ni sehemu ya SNOWSHOE. Packs hayo ni ya kawaida katika jeshi na mountaineering maombi;[4] chuma matoleo ya kwanza alionekana katika karne ya katikati ya 20.

sura ya nje sura pakiti ni kawaida alifanya kutoka alumini, wengine alloy lightweight chuma, na hivi karibuni kushinikizwa polima synthetic au plastiki na ni vifaa na mfumo wa straps na tautly-aliweka mitego ambayo inazuia mawasiliano kati ya sura ya chuma na nyuma ya mtumiaji. Mbali na faraja, hii "kusimama-off" hutoa faida ya ziada ya kujenga mzunguko wa hewa kati ya sura na kurudi wearer. Kwa sababu hii, Packs nje sura ni jumla inachukuliwa kuwa "baridi mzigo" kuliko miundo ya ndani frame. External sura Packs na kitambaa "gunia" sehemu ambayo ni kawaida ndogo kuliko ile ya Packs ndani ya sura, lakini kuwa wazi sura mafungu juu na chini gunia kwa ajili ya malazi attachment ya vitu kubwa. Aidha, gunia mara nyingi unaweza kuwa kuondolewa kabisa, kuruhusu mtumiaji Customize Configuration ya mzigo wake, au kusafirisha mzigo zisizo za kawaida kama vile robo yake mchezo wanyama. Packs Military miundo mara nyingi nje ya sura kutokana na uwezo wao wa kubeba mizigo ya maumbo tofauti, ukubwa na uzito

Ndani ya sura Packs

sura ya ndani backpack is a recent innovation, invented in 1967 by Greg Lowe, who went on to found Lowe Alpine and Lowepro, companies specializing in backpacks and other forms of carrying bags for various equipment. An internal-frame pack has a large fabric section around an internal frame composed of strips of either aluminum, titanium or plastic, sometimes with additional metal stays to reinforce the frame. A complex series of straps works with the frame to distribute the weight and hold it in place. The internal frame permits the pack to fit closely to the wearer’s back and minimizes shifting of the load, which is desirable when participating in activities that involve upper-body movement such as scrambling over rocky surfaces and skiing. However, the tight fit reduces ventilation, so these type of packs tend to be more sweaty than external frame packs. The internal construction also allows for a large storage compartment; a few lash points (including webbing loops and straps for sleeping bags and other large items) may be present, but as the frame is completely integrated, it is difficult to securely lash larger and heavier items which do not fit inside the compartment to the outside of the pack. Internal frame packs originally suffered from smaller load capacity and less comfortable fit during steady walking, but newer models have improved greatly in these respects. In addition, because of their snug fit, the improved internal frame models have largely replaced external frame backpacks for many activities.
