今天看了一篇好文
The Science of Breathability and Its Impact on Raingear Selection and Use
裡面的結論跟我印證了個人的觀念
不必太去計較雨衣材料的透氣度
要去注意雨衣的通風設計
但是我一直不知道為什麼
那只是我個人使用後的感覺...
但是他還把科學根據算出來了
真是厲害阿
特別把他的結論po在板上
給大家參考一下
1. A water-resistant but highly breathable wind shell will always outperform
a waterproof (breathable or non-breathable) garment in drier, windy conditions
due to its ability to breathe significantly better.
2. Be very careful when you try to save weight on raingear by neglecting the
importance of options that increase ventilation (e.g., pit zips, full length
zipper) – you may be decreasing the potential performance of your raingear
drastically.
3. Waterproof nonbreathable raingear with good ventilation features may provide
performance comparable to waterproof-breathable raingear with poor ventilation
features, and must be considered seriously, particularly since nonbreathable
garments (in general) tend to be both lighter and cheaper than equivalent
breathable garments. The weight issue becomes even more important if you
choose to carry a water-resistant highly breathable wind shell in addition
to your raingear.
所以 不必再去迷戀一些透氣數據了
當然 布料的透氣還是有差
不過本體的通風設計相形之下更為重要
好好觀察一下雨衣的本體設計吧
