recently bought a bunch of videos and pics from nylonmedia.de - the site is German, but there is a good amount of shoots featuring Kway rain suits and shiny snowsuits - typical sets feature multiple suit layering - and occasional nudity beneath, but on the whole the I'd consider "softcore". After ordering, a day later you get a password to download your orders. Unfortunately the site is quite old fashioned and extremely basic, but the content is right up your street.
