市面(mian)(mian)上的(de)(de)防(fang)潮(chao)墊(dian)(dian)(dian)種類不少，采(cai)購前(qian)了解一(yi)(yi)下它們的(de)(de)特(te)點并不費(fei)時。充(chong)(chong)氣(qi)墊(dian)(dian)(dian)(AirMattresses)：優點：不用(yong)(yong)說，肯定舒(shu)服(fu)，而(er)(er)且(qie)(qie)可(ke)(ke)(ke)(ke)調節柔軟度(du)，價錢也(ye)不貴。缺點：太重、太大(da)、而(er)(er)且(qie)(qie)容易弄(nong)破。空氣(qi)墊(dian)(dian)(dian)也(ye)不能提供(gong)良好的(de)(de)保溫。此外，對(dui)(dui)肺活(huo)量也(ye)有很(hen)大(da)的(de)(de)要(yao)(yao)(yao)求。(需(xu)用(yong)(yong)嘴來(lai)吹(chui)氣(qi)。)開放氣(qi)室(shi)式(Open-cellFoamPads)：由一(yi)(yi)種象(xiang)海面(mian)(mian)一(yi)(yi)樣的(de)(de)泡(pao)沫(mo)材(cai)料(liao)制成(cheng)。優點：比充(chong)(chong)氣(qi)式更(geng)(geng)舒(shu)適(shi)(shi)(shi)、重量更(geng)(geng)輕、更(geng)(geng)便(bian)宜、更(geng)(geng)保暖。而(er)(er)且(qie)(qie)較重、壓縮性(xing)也(ye)較差(不宜攜帶)、使(shi)用(yong)(yong)壽命(ming)也(ye)較短。 首先必須考(kao)慮暖度(du)、重量、舒(shu)適(shi)(shi)(shi)度(du)、耐用(yong)(yong)性(xing)和(he)大(da)小等依(yi)次重要(yao)(yao)(yao)。其(qi)次要(yao)(yao)(yao)考(kao)慮個(ge)人的(de)(de)主要(yao)(yao)(yao)用(yong)(yong)途(tu)。一(yi)(yi)個(ge)戶外愛好者可(ke)(ke)(ke)(ke)能會擁(yong)有適(shi)(shi)(shi)應不同環境的(de)(de)幾種防(fang)潮(chao)墊(dian)(dian)(dian)。就象(xiang)買(mai)其(qi)他(ta)東西一(yi)(yi)樣，購買(mai)戶外裝備有時也(ye)會讓后悔(hui)，因為實在有太多(duo)的(de)(de)東西需(xu)要(yao)(yao)(yao)考(kao)慮，對(dui)(dui)每一(yi)(yi)樣東西都會有很(hen)多(duo)要(yao)(yao)(yao)求，而(er)(er)在大(da)部分情況下，所有的(de)(de)要(yao)(yao)(yao)求不可(ke)(ke)(ke)(ke)能同時得(de)到(dao)滿足。選擇(ze)防(fang)潮(chao)墊(dian)(dian)(dian)也(ye)一(yi)(yi)樣，有許多(duo)需(xu)要(yao)(yao)(yao)考(kao)慮：絕緣性(xing)(隔(ge)絕身體(ti)與地面(mian)(mian)熱交(jiao)換的(de)(de)能力(li))舒(shu)適(shi)(shi)(shi)性(xing)重量、體(ti)積耐用(yong)(yong)性(xing)從以上條件(jian)中做出選擇(ze)對(dui)(dui)來(lai)說很(hen)重要(yao)(yao)(yao)，而(er)(er)考(kao)慮一(yi)(yi)下戶外計劃可(ke)(ke)(ke)(ke)能對(dui)(dui)很(hen)有幫助。最后，一(yi)(yi)些附屬設計可(ke)(ke)(ke)(ke)能會影響決(jue)定。比如，一(yi)(yi)些防(fang)潮(chao)墊(dian)(dian)(dian)有多(duo)重可(ke)(ke)(ke)(ke)充(chong)(chong)氣(qi)氣(qi)室(shi)，使(shi)得(de)防(fang)潮(chao)墊(dian)(dian)(dian)的(de)(de)厚度(du)更(geng)(geng)容易調節；多(duo)個(ge)墊(dian)(dian)(dian)子可(ke)(ke)(ke)(ke)拼接(jie)一(yi)(yi)起；通過配件(jian)可(ke)(ke)(ke)(ke)將充(chong)(chong)氣(qi)墊(dian)(dian)(dian)改成(cheng)椅子；等等。
