I agree with not going for a combi jacket, and Goretex is certainly one to consider, but search out Paramo Directional Clothing first if you can. www.paramo.co.uk. There gear is brilliant, their ethics commendable, and their after sales ervice second to none. Why do you need an after sales service you might ask. Their gear has a lifetime guarantee, and when I had a problem (not a major one) it was sorted without any fuss, and fast too. Unlike Goretex, which tends to be a bit on the stiff side, Paramo jackets are more supple. A word of caution, their gear isn't cheap, but then quality has a price, and don't forget, with a lifetime guarantee, it is cheaper in the long run. I have walked with a lot of leaders, and inm group holidays, and can promise you all report favourably. You won't find Paramo in Millets, or Blacks (same owner) and retail stores tend to be more in walking areas, especially Lake District, but check out the website and see what you think. Good luck.
