Hi Paul, to be honest, I'm not familiar with the Viper. I can say that the Ventii uses a face fabric that stretches with the membrane, so delam shouldn't be an issue. As usual, if there were ever a problem, you've essentially got a double warranty, from Gore and Arc'teryx. That being said, the best thing about the Arc'teryx warranty is that it almost never gets used.

My Jacket made with VIPER stretch was warrantied by Gore since the membrane didn't stretch underneath the face fabric and leaked in 2 separate locations. Im wondering if they fixed the problems (There is almost no stretch in the membrane).

Arcteryx generally uses their own face fabrics laminated to the pro shell membrane. VIPER was a Gore product (that had 2 way stretch face fabric). Some of the Gore reps or Arc reps maybe can clarify if it is or if this is a completely new product on the market.

Probably real close, I don't remember when the Goretex membrane changed... proshell uses the same Goretex membrane as performance shell... what classifies a garment as proshell is the garment must meet a set of criteria that the mfg must follow specified by Goretex (face fabric, seam taping, stitching, inner backing fabric, etc)... The mechanical stretch comes from the face fabric 434SN, not specifically a new goretex "stretch" material... the Polytetrafluoroethylene (PTFE) Goretex membrane is already inherently stretchy it just needs a stretchy face fabric to become "stretch"...
