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)

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.

Easy to instal and in-instal. Very convenient to store extra luggage.

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

Worth the money. Does the job. It's loads in . Doesn't look the best. The instructions could of been better. I drove 1 hour and half on the motorway and country roads and disnt move . Was windy but not raining so unsure on how waterproof it is but it's pretty thick material. I would recommend.

Wasn’t use / fit, loads of space, secure and dry so far.Used it a couple of times.Easy to pack away when finished with and takes up little room when stored.

We live in Scotland and travelled to see family in England (9 hour drive). The bag was easy to fit and was great for leaving extra space in the car. We travelled through a severe weather warning with heavy rain and high winds for the first 5 hours. Arrived at our destination and the bag had not moved, nor the contents and everything was still dry. Good buy!

Excellent roof bag.have roof rails on my car used only one roof bar at the front bag was too big to fit inside both roof bars. Strapped down very secure. 3 straps either side on roof rails and 2 straps at the front on roof bar.put the slip mat down and then used interlocking mats cut 20ml short of internal size. Fitted the mats inside the bag and you have 15ml of strong sponge to protect car roof. Easy to load filled any gaps.with towels etc. Fully waterproof took all my camping gear .grat bag worth every penny. Cheaper than 500 pounds for a roof box .would highly recommend it.
