Scrub my dismissal.
Just checked out the website. Mine is what they now call the "wind proof jacket". They used to sell it as "waterproof". The new one looks a great jacket for the price, with waterproof zips and seams etc. Bargain at £25.
But, are zips actually guaranteed waterproof - ? Was in a Cotswold Shop a while ago looking for a decent length waterproof jacket. When I commented on the fashion for exposed 'waterproof' zips, I was told they aren't really waterproof.
So where do you put bit & pieces you want at hand but need to be kept dry - ? I asked. Her reply was not to keep anything in zipped pockets that you need to keep dry; oh dear - !
