Gore Tex was supporting the Sierra Club which had launched an all out attack on OHV in the US, to include dirt bikes, 4x4's, snowmobiles, etc. For that reason, Moose and a couple of other manufacturers of OHV clothing quit using Gore Tex and started using material similar but which was not as good. Mine is one of the Gore Tex pieces. The story over the last few years is G-T has finally begun to contribute to OHV organizations and for that reason some of the gear companies are using their products again.
BTW, something very similar happened with Camelbak, which is another of the best pieces of OHV gear I have ever owned. I was part of the letter writing campaign which finally pushed them to make a contibution to the Blue Ribbon Coalition.
The Ford Foundation (Ford Motor Co's philanthropic wing) contributed large amounts to the Sierra Club and their ilk but AFAIK has never put a dime in the coffers of any OHV organization. If someone knows different, sing out!
On topic: gloves are one of those things which are considered disposable in the dirt bike world. Over 3 months they get really tatty and just plain fall apart so I owned an BUNCH of different brands. The ones I liked best, no matter the brand, always had clarino leather palms which were 'pre curved' so they didn't bunch up and cause blisters.
I have an Arai dirt bike helmet, great stuff. I had a Shoei, I had to modify the foam shell so it wouldn't press against the top of my forehead. Before I did that, it would cause a headache within 10 minutes.
