Lightweight waterproof running jacket

GC81

Hi all,
I've got 2 charity races/walks coming up and I'm wondering if anyone could help me find a jacket, might not be wearing it so being lightweight is essenitial but need it to be able to handle June-July weather.
What would you recommend?
Any decent websites you know of? or even ebay shops (as have paypal funds)

Thanks in advanced for any help/advice.

sportsshoes.com sell a lot of discounted running clothing also mandmdirect.com is worth having a look at too, you can buy through cashback sites on these too and save a couple more quid
