I bought an OR Foray 3L recently, and after some initial testing, and seeing some funny patterns on the face fabric, I called & spoke to OR about it. The customer service agent said they believed that this particular jacket had a defective membrane, and advised that I return it or file a warranty claim.
They were very helpful & knowledgeable, and I have a massive respect for OR for keeping their customer service local, using smart, knowledgeable, native English-speaking Americans to help customers... - I was very pleased by that.
I'm on the fence if I replace it with another Foray, or go a different direction.
I'm starting to question whether a Nylon face-fabric is wise at all, since it's hydrophilic by nature. I may be wrong about this, but it seems like Nylons are going to wet out quicker, once heavy rainfall overwhelms the DWR treatment.
Polyester by nature shouldn't be as hygroscopic once the DWR is overwhelmed, and I would expect them to recover faster.
And then of course, there's options like Columbia's "OutDry" that uses no outer face fabric at all, so there's no exterior fabric to wet out. These are looking better & better.
(I say all that with the self-admitted caveat, that "a little bit of knowledge is a dangerous thing," and I've barely acquired "a little bit of knowledge..." So take everything above with a grain of salt...)
