Bought one a few weeks ago, chucked it in the wash and treated it with Nikwax TX Direct. Only used it a couple of times, but I'm very happy with the vents etc. for a summer jacket. I know the material is good, because it's the same as the Taureg in which I went down the road at about 70 last week and did very very little damage to it.
Only change I made was to upgrade the back protector to one that same as the Taureg after the tumble.
