All over Rain Suit for Cyclists: Bikesuit

We have been using Rainlegs over-breeches for some years and found then to be a good way of keeping off the worst of the damp when it rains (http://www.rainlegs.com). Rainlegs cover the upper portion of the thighs and leave the rest of the leg free. This means that you are not bathed in sweat after a few kilometres in the rain - the problem with over-trousers. They are especially useful in showery weather when they don't need to be taken off once it stops raining.
We have just ordered a replacement set of Rainlegs and I noticed on the website that the company is about to sell an all-over garment resembling a multi-zipped boiler suit with a hood and feet cover in a waterproof, breathable fabric called the Bikesuit. This will be introduced to the world at the Eurobike Exhibition in Friedrichshafen, Germany in August. This is all we know. How much it weighs? How much will it cost? We do not know. There is a video of the garment in use on http://bit.ly/bikesuitpress.
The one thing we are not taken with are the partial feet covers as these tend to get holed when the rider puts his feet on the ground. It would be better if you could use the garment for walking in the rain.
