Or, you could think about rain in a different way?
At the start of my hiking career I took the 'traditional' route, bought a waterproof jacket (Paramo Alta 2) and a pair of Beghaus waterproof trousers. I was not happy with the trousers in particular (too hot in the wrong places, a faff to keep putting on and off) so I bought a rain skirt and gaiters, better, but I then moved on to a Vaude Poncho and gaiters. The weakness of the poncho was having to put it over my head when it started to rain and then take it off when it was dry.
This year I decided to separate the issue of wet weather and dry weather, rather than to treat them as a combined problem. My 'better' clothing is now all to do with and only to do with hot, cold, wind, etc. My other group of clothing (much cheaper) is only to do with rain, snow, etc, any weather that can make me wet! I have come to the conclusion that rain doesn't happen so often that I have to prioritise it as my number one problem and therefore have to plan all spending around it.
I now use a £15, zip down the front, long waterproof coat and gaiters. I haven't been able to find a 'better' waterproof coat, say up to £100, because I don't think they are actually made? Rohan makes one but they want £250 which I am definitely not prepared to pay! Just to keep dry, no thank you!
I'm up to the Lakes on 12th April and am then going to walk to Edinburgh. This should be a real test of my new way of thinking about how to keep dry, if it works I'll be boasting about it, if it doesn't I will be apologising for my stupidity.
