This thing is sick. I wear it any time it rains or might rain. The fact that you can turn it into a belt pouch is great. I'm usually a size medium in jackets )and even have an old Patagonia size small jacket I can get into, but it's tight.) And for me, the size Large in this was perfect. Would go up a size. Also, the mesh inside the main zipper looks sweet, but only lets you open the opening an extra half inch, which is a really bizarre design choice IMO. If there was extra material so you could open it wider, it would make sense to me. I ended up having a tailor just remove the inner lining of the zipper, so I can actually breathe if I need to open the zipper. Aside from that, the cut and finish on this is great. I got the green cloud looking one, which I also am a big fan of.
