Now how does the Flashpoint 7D fabric compare to the newer jackets Pertex shield + material?

SummersFlashpoint material is superior - it's a true 3L versus 2.5L laminates.
It won't de-laminate like other jackets that use the Silicone-PU "sandwich" method (SPU/nylon or proprietary/SPU). Also having the nylon on the outside should supposedly give higher wear resistance, I've had my Flashpoint for several months including several days a week of cycle-commuting, weekly trail runs, and a few overnight hikes (mostly as an insect shield) and it still performs flawlessly.
I was initially concerned with the comfort of the material vs. the Marmot Essence, but having used it in heavy rain since found it doesn't cling like I thought it would.
Helps that it has a 20k hydrostatic head and a 40k MVTR.

Pretty phenomenal numbers for such a light waterproof jacket.
Edit: Strangely, after tinkering around the Rab website for info on the middle of the "sandwich" it appears the inner layer is Pertex Shield+ anyway...not sure if this is due to the SS16 update or whether Rab was forced to update their definition of a "proprietary fabric" to a "proprietary process" involving a nylon/pertex/nylon "sandwich".
Also, Pertex seem to have removed their own testing results from their website, but I remember the original MVTR rating for Shield+ was only 20k - hence why I thought the Flashpoint was better than Shield+. So either the Rab website is wrong, the process somehow doubles the MVTR from 20k to 40k, or the middle "sandwich" fabric is actually **Pertex Shield AP**...
