I’ve been wearing this bag everyday for two years, at least 5 days a week. I live in Oregon and the Fall / Winter can be quite wet or snowy. I have never had a problem with this bag, it keeps everything dry on a downpour. The under part of the bag has extra top sail material to protect from the constant stream of water coming off the rear tire when raining. It’s comfortable, and the newer version is much lighter than before. Recently I had some stitching come undone on the original bag I bought in 2022. The warranty process was super easy and I had a new updated bag within the week ( 2024 model). The photo I took also demonstrates how reflective the bag is, first with flash, second without. Would recommend as one of the most water proof durable bags out there! Super happy :)
