I've use this about 5 times since I put it on my road bike. It can pack a lot of gear. I use it for warm layers for both layering up or shedding clothing after it warms up. Looks waterproof when all packed up but I have not ridden in wet weather yet. It mounts very securely. I think this a great value when compared to many other similar products on the market. Nice job Lezyne.
