I'd say it's questionable, until Polartec is able to actually back up the claims being rammed around by it's Hype Train, with field testing.
If anything I'd venture to say that GE might finally be realizing that their tight fisted tactics regarding branding haven't been paying off, since no matter how "internet aged" and clever sounding the "eVent" brand may look on paper(or sleeves), it's almost impossible to freaking search for effectively on the net without using regex. Which is probably a major contributing factor for the lack of brand recognition they have outside of the enthusiast groups (i.e. knowledgeable obsessives like us here at BPL), where as Gore-Tex only pops up one thing. Admittedly it's finally starting to turn around, but 6 months ago if you googled "event jacket", the first page had nothing to do with outdoor gear.
Honestly, the name is stupid, even if the fabric rocks, this is the first time I'm classifying this type of product label fragmentation as a good thing.
For instance, just read the page url: "manufacturers-allowed-to-brand-event-as-their-own"
That makes absolutely no sense unless you know what they're talking about before hand.
Sorry, that's a rant I've been holding in for a while! ;)
Dear GE, love your fabric, hate it's name, can we still be friends? -Javan
