I love my Surface jacket but I did get mine for less than half price, otherwise it is over £100. It seems to me to be better than waterproof as I do not get the same clammy dampness when riding as with Goretex etc. It is not the sort of garment one stuffs into the bottom of a pannier just in case though.
I do have a heavy Goretex jacket which is suitable for winter riding and prety damned waterproof that I would be willing to sell you for a trifling sum (say £20) if it fitted and you liked it but A) It is lime green and B) It has velcro all up the front and has a tendancy to velcro your windpipe to your spine while riding. However I will bring it to PY one morning if you or anyone else might be interested?
