I have used this jacket in the rain many times, it has kept me dry each time. I have used it while longboarding and find it much more breathable than my Gore-Tex jacket. Also, the jacket is not completely windproof (due to the increased brethability) which lends it to high activity pursuits and/or if you tend to be warm, like me.
