I noted that there's a new competitor for waterproof/breathable fabrics: eVent fabrics. Anyone had much experience with it? I noted that REI has jackets in the new fabric, claimed to be so breathable they don't need pit zips (which sounds like a weird way to cut costs). That isn't much news in itself (the industry loves to push out new technologies), but TAD Gear's new hardshells also use eVent, which is a completely different market. So is this new stuff worth trying out? I've never been amazed with Goretex.
