首先談一談帳篷。
這些年來,帳篷的革新,以及在戶外生活中的普及,使得這類產品的分類越來越明細,而各大品牌下都能發現一個系列,即:SUPERLIGHT,HYPERLIGHT或ULTRALIGHT超輕系列帳篷,輕意味著PACKLIGHTLY,意味著更小的打包體積,在不是惡劣的環境下,只滿足徒步及穿越的需要時,可以告別沉重和巨大的困惑,取而代之的是享受科技進步帶來的舒適和輕鬆,背包的時刻並不總是負累。從前幾年的EUROHIKE225(3。5KG)的流行,到ACME小兩洞(3。2KG),再到現在的snowwolf徒步營(2。6KG)。帳篷的發展趨勢是輕量化。
在此,先介紹幾頂帳篷,然後再加以分析比較,比較的目的,並不只是指標上的對比,而是通過比較,理解設計的思路,感受科技的進步。
這些帳篷都為獨立支撐設計也叫穹頂式帳篷,1人,1-2人或雙人帳,單層,單層加半層外帳及雙層帳,基本上為滿足三季需求而設計。
