I bought this pullover to bring with me on an Alaska cruise next month and decided to give it a test run by wearing it on a long nature walk in the rain yesterday.  This pullover kept me mostly dry over the 90 minutes I spent walking in a gentle, steady rain, but it was clear by the end of my walk that I was reaching the limits of this pullovers water resistance.  The fabric was completely saturated and was starting to get the fleece I was wearing under it a little damp.  Not so wet that it reached the t-shirt I was wearing underneath the fleece, but definitely damp to the touch.  I don't think Id trust it in a down pour for more than 20-30 minutes, but itd work fairly well if you're only spending enough time in the rain to go from place to place.

The good news is that it dries incredibly quickly, and works great as a top protective layer to keep you warm.  It was in the 40s and obviously wet during my walk, but I felt toasty warm when I wore this over a t-shirt and fleece.  I love how small it packs up and I really love the gigantic pockets it has.

If I was judging this pullover as a lightweight, breathable windbreaker Id give it a 5, but if I judged it as a raincoat Id give it a 3.  So Im splitting the difference here and giving it a 4.  The rain protection will probably be sufficient enough for my cruise so long as I slip inside or at least under cover every 45 minutes or so so that the pullover has the chance to dry out a little every now and then instead of staying completely saturated with water.
