Cheers for everyone's input and suggestions so far have been looking up the various options and as asked above a good point .... I'm UK based right on the south coast and most of the cycling I'll be doing is relatively flat with a mix of mainly off road tracks and about 30% on roads on a mountain bike doing typically between 15 and 25 miles per time.

Excuse my ignorance but if I don't ask I'll never know the answer but what is soft shell ??? I'm guessing it's a softer outer that may be more breathable but could be well wide of the mark with that???
