In reply to Removed Userplodding painter:
I recommend investing in either an extremely lightweight emergency jacket and a good softshell or a standard Goretex shell, as in the summer, spring, and autumn I would mainly use a softshell as there is no need because it is not as likely to rain. (and everyone has to admit that a waterproof jacket can't actually be breathable) The montane alpine shift jacket is an excellent option as it is lightweight, packable, and also durable. it is about halfway between an emergency shell and a hardshell jacket. a good tip for any montane kit is to look at the eBay seller MountainKit. they sell montane samples at great prices. I would also recommend trying to find Polartec neo-shell, it's lightweight, and according to my dad, more breathable than gore-tex, however, it is not very durable. another ultralight option would be the outdoor research helium 2 jacket.
another option is the marmot precip or the Patagonia torrentshell, they are both very cheap and relatively lightweight. My dad used to have the Precip and he said it's one of the best shells he has ever owned. and because it is cheap, you can abuse the hell out of it without worrying too much about it. Also, Patagonia has a lifetime warranty for everything, so no matter what, they will repair your kit or replace it.
I also used to use a standard Goretex shell, I used one for all-season usage for climbing and hillwalking, as they are light, but will definitely (speaking from personal experience) survive hail, strong rain wind, snow, etc. For example the Patagonia calcite jacket. (the one I used was the ME quarrel, still up for sale and in pretty good condition so message if you are interested (size small btw))
Personally I would go for the montane alpine shift for 3 or even all-season use and invest the money in a quality softshell such as the montane dyno-stretch, it is an excellent combo and will serve you a long time. If you haven't used a Montane kit before it is absolutely bomber, probably even better than more expensive brands such as Arcteryx.
