Love it!
I Love this bag it will be my go to if theres going to be any chances of weather. It doesn't feel different from just a normal trail running vest and all my stuff stays dry. Pack is very stable and lots of room in the pack and front zipper pockets are deep. Water bottle pockets seem a little tight but might just be that its so new. 5'11,175lbs
