Nice jacket for day to day rain
This jacket works great for almost all wet conditions. the only problem I have encountered was when I was in torrental rain (no pun intended) and I had to clear a gutter. I was reaching up the whole time so the pit zips were directly exposed to the rain. there are storm flaps over the pit zips but they do not totally cover the non-water resistant zippers, so a small amount of water got in.
But to put it into perspective I think all pit zips would leak in those conditions unless they had a truly waterproof zipper but there are none with waterproof zippers on the pit zips.
