Ultra lightweight waterproof jacket.

I have a winter Altura Jacket which is quite heavy, and was wondering if anyone could point me in the direction of a lightweight, packs small, waterproof for the summer please?

Thanks for all of your suggestions. I ended up getting this one. Waterproof, light and cheap.
