thanks for weighing in here. now that you mentioned Exped, i remember reading your posts on this subject. sorry for the "senior moment" and forgetting who it was who mentioned that (and where you mentioned it).
the Polaris appears to be quite a large and heavy mountaineering shelter. does Exped use eVENT in any smaller/lighter tents?
i also remember, now, that i questioned whether that was really eVENT or just another ePTFE laminate (not sure if i posted such a comment or just thought it to myself). can you refresh my memory as to the source of your info, please? i'm a bit surprised that GE would let it in throught the "backdoor". i, naively (what do i know about legal matters???), would think that GE would still be "on the hook" legally in our litigious society if a foreign mfr. sold eVENT tents in the USA. after all, isn't ID a Canadian (foreign) company? sure that are, and they can't, any longer, use eVENT in tents that one can cook in, right?
would appreciate you elaborating a bit more on your post and respond to my questions if you care to. not saying i'm right. just thinking out loud and hoping that by doing so, you can see where i'm coming from and can set me straight by eliminating some of my confusion.
