In reply to penney1990: all high-end waterproof jackets are waterproof and breathable (to an extent).
I would recommend trying on a number of jackets as each brand has a different cut to others and might not fit you properly (an important factor when being used for climbing etc).
the best fit test you can do is try one on with the thickest fleece you intend to wear, zip it up and raise your arms above your head as if you are reaching for a top shelf. you should notice little lift around the waist. also stretch your arms out in front of you and it shouldn't feel too tight across the back.
