I used this jacket for three weeks in alaska this summer. it was absolutely FANTASTIC. water never seeped through once. not even in torrential rain. one day we hiked 15 miles in rain with fog so thick you couldnt see 10 feet in front of you and i was dry. however the reason it did not get a 5 was because just recently the stitching ripped on the left pit zip as i was trying to open it. however, again, the gearhead is set me up with a return and a full refund so all is well.
