In the U.S., Paramo's influence is very clear in garments such as Patagonia's Infurno Jacket ($250), which works along the principle of getting moisture out, rather than keeping it out. Naturally, any number of fabric and gear makers are trying to do the same thing. Polartec's newer fabrics, such as PowerDry, are designed specifically to move moisture away from the body, while most rainwear makers are adding extra vents. Actually, Paramo clothing relies to some extent on the gimmick of venting the hell out of it and including roll-up sleeves. I mean, at that point just take the damn thing off!
I'm reluctant to say Paramo is "all they say it is" because I don't know who "they" are or what they're saying. But, it makes perfect sense, and all reports I've received are good, particularly for aerobic activities in cold, damp weather. I think in the U.S. we've been too heavily influenced by the "weather armor" conceptthe idea that we can buy one garment and stay dry and comfortable. The Gore folks, of course, have helped foster this idea. But in many cases, sweat and condensation are more soaking than rain. Paramo stuff recognizes this, and works with it.
