Holds a lot and is watertight
We were taking the last load from the house prior to moving but did not want to rent a trailer. The RoofBag was perfect! It was shipped quickly, was inexpensive, and held a lot of stuff. We went through driving wind/rain and the bag did not leak at all.It held tightly to the roof although we did follow previous suggestions to put a squishy rug pad under it. No reservations at all.
