Got caught in the rain this morning, so ducked into Primark and bought a raincoat for £9. Doesn't look obviously cheap/crap, the hood is really roomy (unlike a lot of raincoats) and you can fold it into one of its pockets and zip it up to put in your bag when not in use. Already thinking it might be my best buy of the summer so far! Thought I'd share in case others here want an alternative to grappling with an umbrella :)
