Bought this for a bear hunting trip out west. Haven’t had the chance to test it walking through brush, but, I did play 18 holes in a down pour wearing the jacket. I have to say I stayed reasonably dry. The jacket was light enough to not interfere with my swing, I stayed cool while playing, and my shirt was only mildly wet after the 4 hours on standing in the rain. The experience solidified my trust of this product. Would recommend.
