I’m very curious as to why REI took the gamble to go with eVent in the first place? Possibly cost, with the hope that the superior product would win over customers after they use it?
I talked with Montane last year and they replaced eVent with Gore-Tex on all their higher end shells. I just met with Mountain Hardwear yesterday and learned that they are bringing Gore-Tex back as well, again just for their most expensive pieces. Both told me that it’s because of brand recognition and customer perception.
Rab still uses eVent, but only in a select few shells. For other shells, like the Kinetic and Kinetic Plus, they have their own proprietary stretch waterproof fabric. It looks like most of their shells are using Pertex+.
