Great jacket to keep you dry. I wear it on rainy days when I have to walk from my parking garage into work. I have also worn it now on a run and a hike in the pouring rain, felt like it kept me plenty dry even though I ended up sweating a good bit but thats to be expected in this type of material. Also love that it packs so small into itself, so I can carry it everywhere and take it on back packing trips.
