I got this for my spring break trip in New Orleans. During a cemetery tour there was a huge storm, full on  torrential down pour, lightning, flooding but the 2 hour tour was rain or shine. I thought there is no was this thin little jacket will keep me dry, my shoes were soaked and soggy, my pants were dripping, I couldn't grip anything with my hands because they were wet with nothing to dry them with but I got back to my hotel room took off my jacket and everything from my hips up were bone dry! What?! It looked like I walked half way into a pool with my clothes on. Ive also worn it to Disneyland a few times in the rain and it worked just as good everytime.  This jacket is amazing its super thin and lightweight, it wouldnt really keep you warm but I sized up so I can comfortably  wear a sweater underneath, its very packable you can fold it up very small and it easily just ties around your waist without being bulky. The Velcro adjustment straps for the wrists are nice and so is the adjustment around the bottom and hood so the jacket will stay in place wherever you want it and the pockets are big enough to hold an iPhone X. 100% worth the $18 I spent on it and I would still get it if it was more.
