Hc4runner, actually W. L. Gore's representative didn't literally say the effectiveness would last as long as the garment, he said the Suppressant membrane was guaranteed to last as long as the garment itself. Also, Goretex states that it can can be washed with no scent soaps and that the activated charcoal would not wash out because the charcoal is imbedded into the Windstopper material. I take this to mean it can be washed regularly or at least more often than the others plus keep its human odor holding qualities. You will have mail soon as I will forward the rep's email reply to my questions.

As some above have posted, improvements are being made all the time and all 3 look good to me to try. For me I am going with the Suppressant for now.
