As title really? Got full Gortex 2 piece Textiles which yes, I know are waterproof anyway but would like to have a 1 piece rain suit for Touring Hols which can go over the Gortex if I know it's gunna Piss down all day. The internal Gortex membrane might keep me dry but it won't stop the majority of the Textile overlay getting saturated and heavy from a days wet riding will it!
Have used a WEISE over suit for 20 years, used to despatch ride in it, annual spraying with that nikwax tent gear keeps it waterproof, still available, gets warm putting it on then stays warm.
Keep a look out on eBay, I got an unused frank Thomas aqua pack for pence, I'm hoping this year it will also be unused
