Was the company I had in mind, though there could be others. Not sure if you want to go that light, but the large jacket is 165g, and the large rainpants are 113g.
You'd be wandering around with a pretty cutting edge fabric, so there's not a whole lot of experience about with it. I'm thinking of making a bivy sack out of some of it, having had good experience with eVent and cuben fibre seperately thus far - why not mix em!
