刚才初步搜了一下,貌似宣传是这样的:
What makes OutDry different is that the waterproof/breathable membrane gets bonded directly to the fabric, instead of loosely lining it (as with Gore-Tex). Bonding the two together eliminates any air space or gap between the outer material--say, leather--and the waterproof/breathable membrane. What's wrong with that thin layer of air? OutDry proponents say it adds bulk and traps moisture, which contributes to a colder, clammier feel.
