COSTWAY15/21 Cubic Feet Car Roof Bag, 100% Waterproof Roofing Cargo Carrier with Anti-Slip Mat, Combination Lock & Straps, Rooftop Luggage Storage Box (Black+Orange, 15 Cubic Ft/424L)

these are very good. holds a lot and is very secure comes with a little mat to protect car

This is an absolute bargain of a product. It was really easy to attach to the roof, especially after I realised not to tighten the straps until after I'd loaded the bag, and that the zip goes right around 3 sides. So simple to hook the brackets under the door rubber. It held firm in some decent winds, and was bone dry after a few showers. Highly recommend

Withstood a 6 hour drive, there and back, on top of my Ford Focus (no roof rack, no bars).Loads more space and far cheaper than a roof box. And super easy to fit (10 mins maybe).Only minor gripe is there are two additional straps on the front and back (four in total) that need tucking into your door as there are no hooks for these. Assume they're for use for when combining with roof rack/bars.Be warned, it'll need a clean after the motorways as it picks up its fair share of insects!

Did the job, plenty of extra storage for growing family, it was easy to put on (although would have liked a few more instructions). Kept everything safe and dry for a ling journey and most importantly for us was super easy to fold back and get into the bag. Folds down to be very compact so easy to store when not in use.

This is an excellent product. I used it on a roof rack. Most cars will take up to 75Kg on the roof (including rack). This bag will have no problems with that. No ingress of water despite heavy rain over a seven day period. Fixings are strong and plentiful. The fact that it pulls down to the height of the contents so that it always maintains the lowest possible profile helps with efficiency. I detected no wind noise.I have not used it without the roof rack so cannot comment on that, but is made using the rack really secure, rain proof and easy.

Brilliant!

Going to write a pretty long review as was very dubious about buying this roof bag and hope it helps someone else. When buying this roof bag, consider how many times you will be using it a year as using once/twice a year is fine but I personally don't think I would be happy using this lots. If you are practical then this roof bag should present no problems fitting and securing, if you're not then go to Halfords, buy and get them to fit roof bars and top box to your car. When packing, place your bedding, towels etc on the bottom covering the whole of the roof bag to protect your roof. Easy to secure with only having to use the 6 straps provided and stayed in place upto speeds of 90 mph (on the Autobahns) so no worries there at all. Didn't have to retighten straps as made sure it was fully loaded but may shift if not packed properly. When it comes to waterproof, we drove through two yellow warnings for rain and it was constant both there and back and absolutely no leaks at all, clothes, food, bedding and towels all dry. We were going to hire roof bars and top box but down to cost this beats it hands down. To sum up, cheaper than hiring a top box, no worries about storing a bulky top box in the garage as folds down very small and can be stored in a cupboard, definitely waterproof, good value for money. Would recommend

Absolute game changer for holiday packing.However not easy to install ...says to clip between door and seal ...this does not work if door seal is glued down. Had to 'get crewtice' with some long ratchet straps attached above heads through the car and to anchor points in boot but once fixed gave us so much more room in car for kids and dog!
