Have you ever actually read the GoreTex guarantee? Did you know it comes in different grades, including a motorcycle-specific grade manufactured specifically to withstand extended highway speeds (and FULLY guaranteed)? Your blanket statement "Rubberised yellow work pants are the ONLY thing that will keep you dry in extended rain." seems to exclude all the stuff I've used over the years that wasn't rubber pants and still worked. Lots of it. Sure, I've had stuff that leaked from new (who hasn't ), and stuff that was "temporarily" waterproof, but I still also have garments over 25 years old that have NEVER let in a drop, and they aren't rubber. I also dispute your claim that your "rubber" pants are over 40 years old - rubber perishes mate, they should actually be dust by now. I suspect they are actually plastic.
