Anyone use a PI Attack jacket?
 

I'm looking for a rain jacket and I've looked at Gore, Showers Pass, J & G and others. I'd like something I can try on rather than ordering off of a size chart. The Pearl Izumi Attack fit really well and was comfortable. I'm just wondering about the breathability and true waterproofness (is that a word?).

A BF search came up with nothing and even a Google search showed no usable reviews.

If any of you have a PI jacket with the Optik WxB fabric, may I please have your opinion.
