The roof bag is high quality and waterproof. The zipper takes a bit to zip around the corners due to the waterproof flap that covers it. We also purchased the mat to keep it in place on the roof of the car. We travel with our daughter and son in law and two granddaughters so we were always running out of room in the car. We bought the small one and it holds more than we expected. We are very happy with our purchase.
