Today's question: if you wore a breathable waterproof jacket inside out, would it let the rain in?

No reason, I'm just curious. And I've never really understood how these superfunky hi-tech fabrics work.

Or do not work, in the case of my cheapo shell waterproof, which lets the rain in anyway. It's surprisingly hard to tell, but I'm moderately confident I'm wearing it right way out.

Otherly, this morning I misheard one of my colleagues talking about going diving in a twinset. Except it turns out I didn't mishear, he just meant something different by the term.

I'm sticking with my mental image. Though surely the obligatory string of sensible pearls would get in the way of the regulator?

Gortex fabric works by being stretched in a way that creates a barrier that is porous to water vapour but has holes too small for droplets. It is usually backed to a wicking layer that you really want on the inside. So yes, but it will get much heavier and not breath as well.

Similar fabrics, I have no idea.

enjoy :)

that company or Rohan stuff or an Event fabric are the only things I will use.

(FYI Paramo is also the choice of the Welshish (Breconish) mountain rescue lot - they were offered freebie stuff from other manufacturers or a discount off Paramo. They bought Paramo. there you go, enjoy :)
Note: I use http://www.paramo.co.uk/en-gb/garments/detail/index.php?pgc=NIKWAXWINDPROOFSMOCKFUERAUNISEX on my bike for 6 months of the year.
