Car Rooftop Cargo Carrier Bag, 20 Cubic Feet 100% Waterproof Heavy Duty 900D Car Roof Bag for All Cars with/Without Rack - Includes Anti-Slip Mat, 10 Reinforced Straps, 6 Door Hooks, Luggage Lock

Great bag. Waterproof - strong material easy to use. Lots of space ! Came with straps to secure a perfect fit.

I bought this for a recent trip, and it worked well. The carrier is very large and holds a lot. Because it is large and has multiple straps for securing it to the roof, it is tricky to install. I found the best approach is to open the zipper and set in on the roof. Then set a few luggage bags into it. This will help to keep it in place and hold its shape. When you get it full, you can zip it up and attach the straps. The traps latches are plastic so don't over tighten them. I pulled one very hard and I thought I broke it, but it only slipped out of the clasp. We took it on a 200 mi drive with it strapped to our luggage track. It stayed in place perfectly. It might not hold up for everyday use, but for the occasional trip once or twice a year, it should be fine.

1300 miles of interstate deriving it never moved, was quiet and never leaked despite rain for hours that eventually made us stop driving. One of the best values I have ever purchased. Packed to the brim. Amazing what this held! The tool to pull back weather stripping for installing the clips for roof mounting was included along with the anti slip mat. Instructions were clear and accurate.

Worked fine for a long trip and lots of rain. Seemed to be a lot of space! Pay more attention to strapping down Hahaha a photo from up in the St Louis arch, but you can see it on top of the van

Returned bc we didn't need. Thank you. Arrived quickly and is a quality product.
