After taking time to load items as neatly as possible, and arranging evenly from side-to-side, and front -to-back it zipped up and the Velcro sealed up securely. The four corner straps secured the bag in place. We traveled mostly interstates at speeds of 65 to 80 mph, and it never moved. Fortunately we did not encounter any rain so I can't comment on water repellency. I will say the material feels thick and of a water repellent type of material with the Velcro flap to seal the zipper.
