What is the difference between the windwall...
What is the difference between the windwall 1 and 2, and the pamir wind stopper?
Windwall 1 - 100 weight fleece that has 14 CFM windproofness.
Windwall 2 - 200 weight fleece that has 10 CFM windproofness (lower the number, the more windproof). Also has slash pocket on chest.
Pamir - Gore Windstopper textile, which is totally windproof (0 CFM)
