市面(mian)上的(de)(de)防潮(chao)墊(dian)(dian)種(zhong)類不少，采購(gou)前了解一(yi)下它們(men)的(de)(de)特點并不費時(shi)。充(chong)(chong)(chong)氣(qi)(qi)墊(dian)(dian)(AirMattresses)：優(you)點：不用(yong)(yong)說，肯定舒(shu)(shu)服，而(er)(er)(er)且(qie)可(ke)(ke)調節柔軟度，價錢也(ye)不貴。缺點：太(tai)重(zhong)(zhong)、太(tai)大、而(er)(er)(er)且(qie)容(rong)(rong)易(yi)(yi)弄破。空氣(qi)(qi)墊(dian)(dian)也(ye)不能(neng)提(ti)供良好的(de)(de)保溫。此外(wai)(wai)，對肺活量也(ye)有(you)(you)很大的(de)(de)要(yao)求。(需(xu)用(yong)(yong)嘴來吹(chui)氣(qi)(qi)。)開放氣(qi)(qi)室式(shi)(Open-cellFoamPads)：由一(yi)種(zhong)象海(hai)面(mian)一(yi)樣(yang)的(de)(de)泡沫材(cai)料制成(cheng)。優(you)點：比充(chong)(chong)(chong)氣(qi)(qi)式(shi)更舒(shu)(shu)適、重(zhong)(zhong)量更輕、更便宜(yi)、更保暖。而(er)(er)(er)且(qie)較(jiao)重(zhong)(zhong)、壓縮性(xing)也(ye)較(jiao)差(不宜(yi)攜帶)、使用(yong)(yong)壽命也(ye)較(jiao)短。 首先必須考(kao)慮暖度、重(zhong)(zhong)量、舒(shu)(shu)適度、耐用(yong)(yong)性(xing)和大小等依次重(zhong)(zhong)要(yao)。其次要(yao)考(kao)慮個人的(de)(de)主要(yao)用(yong)(yong)途(tu)。一(yi)個戶外(wai)(wai)愛好者可(ke)(ke)能(neng)會擁有(you)(you)適應不同環境的(de)(de)幾種(zhong)防潮(chao)墊(dian)(dian)。就(jiu)象買其他東西(xi)一(yi)樣(yang)，購(gou)買戶外(wai)(wai)裝備有(you)(you)時(shi)也(ye)會讓(rang)后悔，因為實在(zai)有(you)(you)太(tai)多的(de)(de)東西(xi)需(xu)要(yao)考(kao)慮，對每(mei)一(yi)樣(yang)東西(xi)都(dou)會有(you)(you)很多要(yao)求，而(er)(er)(er)在(zai)大部分情況(kuang)下，所(suo)有(you)(you)的(de)(de)要(yao)求不可(ke)(ke)能(neng)同時(shi)得(de)(de)到滿足。選擇防潮(chao)墊(dian)(dian)也(ye)一(yi)樣(yang)，有(you)(you)許多需(xu)要(yao)考(kao)慮：絕緣(yuan)性(xing)(隔絕身體與地面(mian)熱交換(huan)的(de)(de)能(neng)力)舒(shu)(shu)適性(xing)重(zhong)(zhong)量、體積(ji)耐用(yong)(yong)性(xing)從(cong)以(yi)上條件(jian)中做出選擇對來說很重(zhong)(zhong)要(yao)，而(er)(er)(er)考(kao)慮一(yi)下戶外(wai)(wai)計劃可(ke)(ke)能(neng)對很有(you)(you)幫(bang)助。最后，一(yi)些附屬(shu)設(she)計可(ke)(ke)能(neng)會影(ying)響決定。比如，一(yi)些防潮(chao)墊(dian)(dian)有(you)(you)多重(zhong)(zhong)可(ke)(ke)充(chong)(chong)(chong)氣(qi)(qi)氣(qi)(qi)室，使得(de)(de)防潮(chao)墊(dian)(dian)的(de)(de)厚度更容(rong)(rong)易(yi)(yi)調節；多個墊(dian)(dian)子可(ke)(ke)拼接一(yi)起(qi)；通過配件(jian)可(ke)(ke)將(jiang)充(chong)(chong)(chong)氣(qi)(qi)墊(dian)(dian)改(gai)成(cheng)椅子；等等。
