It's a light weight and compact jacket. I've been using it for about 3 months, mostly for motorcycling in the rain. Also used it on a trek where it rained for 8hrs. For motorcycling, it's okay. Keeps me dry even in heavy rain, and winds. But those are for fairly short trips not lasting more than 30 mins. On the long trek, it was ok during the first few hours. But at the end of the day, the humidity, the rain, the sweat, it got very damp.
