Just to throw my tuppence on the pile, Carlo, it's a fantastic shirt. Even when too hot and sweating (which usually happens when crossing through woodland from a cold and exposed hill top) it's easy to adjust the vents and roll the sleeves up. Aside from the inherent drawbacks of synthetics, and of course the minor point that you look a total bottom in the pub wearing one of these, it's the sort of shirt you find yourself reaching for first and wearing forever. I hardly ever wear an actual waterproof anymore.
If you need to add the extras, I should mention that Buffalo mitts tend to be a size smaller than you think they are and the expedition hood is far superior to the regular model. I wore my Buff with the expedition hood in Lapland, and it was superb, but it really is warm... maybe one of the lighter Buffalo jackets would be better for general use.
