ps. I just looked, and my jacket isn't the Whoosh. That (and the hydrocycle) are both Entrant coated, but my jacket is 3-ply goretex. They actually don't make mine anymore it seems. My pants are Entrant though and keep me quite dry.
It's nice because I don't think it necessarily looks like a cycling jacket, so it makes a good general-purpose wet/cold weather jacket. Plus I have the longest arms in the world, and as a cycling jacket it's cut long in the arms, which is nice.
Darkmother: these things still get a little swampy when you're riding hard, but it's still breathable. If I was going on a longer ride in the rain I'd probably go for something that would keep me WARM rather than DRY. Mine does have pit zips though, which I use pretty regularly.
