Realise this is an old thread but after my experiences I thought I ought to post...
In short, I've had two of these since August 2011 and both have failed/de-laminated, which might be an indication of poor build quality or (very likely) a bad batch.
Bought a yellow one in August 2011 - on back of Best in Test in Trail etc. and was initially very impressed with the lightness, apparent toughness and definite waterproofness/breathability on the hill (although the fit does leave a bit to be desired if you have a remotely athletic/V-shaped chest and normal-length, humanoid arms...). With very few wears in August/Spetember, I took it for a week's Munro-bagging (3/4 walks with 2/3 wears from memory) in October and suffice to say it went black/transparent around key stress areas and de-laminated. Took back to shop. Got replacement... (~Oct 2011)
Replacement has lasted till now, which is better than the first but has de-laminated in more places/more badly...
As I say, it's a very light and has been very waterproof/breathable till now but two failures like this is pretty bad. Still, could've been a bad batch, so I'm at a loss as to what to do/replace...
