"...I could easily feel the wind through the Event (or some sort of cooling) ..."
I'm guessing that "some sort of cooling" is the issue, not airflow through the laminate.
From Mr. Nisley:
"Cubic feet per minute per square meter (CFM) is a measure of the wind resistance or air permeability of a fabric. The higher the CFM, the greater the volume of air passing through.
"Traditional barriers like H2NO, Gore-Tex, eVENT, Triple Point, Entrant, and other respectable waterproof breathable technologies all have a 0 CFM rating. If you are just sitting still or doing camp chores a 0 CFM garment will block all wind and keep you the warmest. Both eVENT and Gore-Tex Direct Venting achieve this with a pore size of about .2 microns.
"With the advent of soft shells and more breathable fabrics, the air permeability argument becomes complicated, sometimes heated. If you are backpacking, you can afford a bit of convective heat loss. You need more breathability to move the extra moisture you create through exertion. And a fabric with 0 CFM doesn't provide it. Fabrics that measure as much as 5 CFM are still functionally windproof: that is, you don't feel the breeze come through. And they afford much greater comfort with the high exertion rates during backpacking. Popular wind shirts, like the Patagonia Houdini, fall into this class as do the best soft shells. The average pore size for this class of fabrics is about 20 microns or 100x times larger than eVENT. Any larger pore size will result in more than 5 CFM. After 5 CFM you can start to feel the wind through the fabric."
