In reply to angry pirate:

Yes; it's not anywhere near as close a weave as the microfibre Pertex fabrics. Closer to Equilibrium (which is also a dual-weave stretch soft shell, but lighter).
The 'kiss test' is pretty good at testing fabric wind resistance; press fabric to lips, and blow. Use your hand to feel how much of your breath passes through the fabric. You soon manage to calibrate your test...
I'm still fairly convinced that the Exodus is made from the same fabric as Decathlon use for their Mountaineering Trousers. I've been hoping for some time that they'd start selling a half-decent soft shell jacket made from the fabric, maybe under the same Simond branding... No joy yet.
