How good is it well, lets says that i have bought many rain jackets from top brands like gore bike wear etc, over the years for long distance bikepacking or touring specailly through moonsoons in Asia , they all make big promises with very good marketing. and all have failed within few months .. Not the case with this jackets .. i tell you how good it is. It rained every day for pass 3 months the day this jacket arrived and i opened the box the sun came out Still waiting to test will update once it rains but .. they say it keep you dry i am riding every day still dry lol love it
