R.e. the Gore One Activeshell – here’s my review on grit.cx. http://grit.cx/reviews/15092 I’ve had it a year now, and it is by far and away the best ever waterproof jacket I’ve used in terms of breathability.
There is a massive downside for off road riding though, and that is its fragility. The fabric isn’t very tough, and I know of one other tester who shredded his against a wall while riding along. Gore also don’t recommend that you wear a pack either, as the friction will wear through the fabric.
In short – if you are road riding, and can afford it, buy one. If you are planning on riding offroad, wait for a generation or two down the line.
Columbia do something called Outdry fabric, which is also doesn’t reply upon DWR for beading. I don’t think it is as breathable as Goretex, and they don’t do any bike-specific cuts. But… it works well.
Finally, I’m testing an Alpkit Gravitas waterproof – I’ve been impressed. It’s very light. And an Upper Downs jacket, which is beautifully cut and functions very well, but is at the upper end of the price range for a jacket.
