I know the committee didn't want to name particular items of kit, but for years the Mistlite 130 has been sold in shops as:
waterproof (rightly or wrongly)
and meeting FRA requirements
As far as I've seen the mistlite were always sold as water resistant, which isn't the same as waterproof, and they do meet the FRA core standards for wind proof which has now changed to waterproof. They never had taped seams or a proper waterproof membrane.
