I've got one of these ('cept in a different colour). It's pretty expensive and I waited a looooong time to find one on sale, but it's also pretty good - light, completely windproof and definitely more breathable than anything else I've owned to keep me dry. I do sometimes wish for pit zips on really long, draggy climbs, but I wish for a lot of things during those . It's seen enough rain that its waterproofing is only good for about three hours these days, but that's something that will happen to any jacket in the end and your commute probably isn't as long as that anyway.
