Well, for the most part, TNF focuses on 'fashion' (i.e., making shitty stuff that the average person wears, but fits like a snuggie) these days. But, they have a longer history of making excellent technical gear. SF is not the right place for the OP to be asking this question. And, who cares about 'authentic' (whatever that is) when we're talking technical gear? Good point. I guess asking for advice on non-stylish gear in the "style" forum wasn't well thought out by the OP.
