I'm working on my second Showers Pass jacket. The first one I bought in 07. It was their Century model. Later redesigned into the present Elite 2.0. Anyhow the first one lasted about three years of year round use. Used as necessary in good weather. And everyday in winter as an outer shell. Towards the end, the jacket zipper started to malfunction. As in, where you zip it up and it comes apart in the middle. And you have to try to re-zip it to get it back together. Also the DSW (oops, I meant DWR) started to wear out. And I would rejuvenate it with some Nikwax, which did the trick.
Jacket #2 was the Elite 2.0. purchased in winter 2010. Shortly thereafter the zipper on the chest pocket came apart, and I can no longer zip it shut. I expect to get the same three years before another replacement is due. When that happens. I'm going to buy the waterproof, breathable rain jacket from J&G cyclewear from Oregon. They get good reviews, and are cheaper.
