Signstek Car Roof Bag,21 Cubic Feet Large Roofing Cargo Carrier Bags Waterproof Soft Rooftop Luggage Storage Box for Any Cars With/Without Roof Rack/Rails/Bars

This roof bag it great! I got it to replace an aging roof box that I had for many years, and was hoping it would be a suitable replacement. I did not disappoint. The straps are sturdy, the capacity is great, it was soooo easy to install, and it is waterproof (we drove through a biblical scale downpour and everything remained dry. I got soaked with seconds when we stopped in it!). It was really easy to take off and put back on so we didn't have to drive around with it on the whole time we were on holiday. It is definitely worth every penny.

Brilliant quality and deal. It's bigger than I thought, which is a bonus. Perfect for all of my camping stuff and freed the boot space up. Waterproof and can be used with or without roof bars. Instructions were easy to understand, with removable straps

Excellent product. Well made and a good size. Fitted car really well and didn’t move at all during the journey. I didn’t use the door clips but used all of the other straps to secure to the roof rails. It would have been better if the straps were fitted with ratchet tighteners as it was a bit time consuming adjusting the straps to fit. I didn’t put heavy items on the roof as I didn’t have the strength to lift them onto the roof, but I did fill the bag to its capacity. I would not put valuable items in it as I think it would be easy to break into when left unattended compared to the hard shell type of top box. However, it was very easy to use, affordable and I would recommend this product.

Used today to carry clothes for our holiday. Weather was wet and we travelled on the motorway, all items dry inside and arrived safely. Easy to use without roof bars. We attached to our Mokka which had a tiny boot. Wish we have had for this sooner.

We drove all over France & Spain and it worked a treat. Loads of room inside and easy to set up.

I wasn't sure what I would recieve but I needed extra space for camping supplies. This bag is enormous and kept everything dry in torrential rain on a long drive. No sounds while driving. Made from thick good quality material. Took all the sleeping bags,back packs, tent Groundsheet and carpet(large tent) Pillows, wellies, boots, coats and still had a lot of room in there. Very impressed. This one was the largest and had to move the roof bars as far as they could go but comes with clips if you don't have side bars or racks. Comes with anti slip and protective sheet for the roof of the car too. Installed myself and was brilliant

Points to note: • The two front and two back straps don't attach to anything if you are using without roof rack/bars. • Make sure all strap ends are tucked in well or tied to other straps to avoid them hitting against the car whilst driving. • When re-placing the rubber seal over the hooks,make sure you hear it "click" back into place. • The obvious point is when fitting,place on top of car (with mat in place), with the lid hanging down over your windscreen and then the non-zip side will automatically be facing front. • When zipping it up,have the two zip ends meet at the side rather than the back,just to ensure it's more weatherproof. • Always remember to firmly press all the velcro down after zipping. • Remember to peel the protective layer of film off the reflective strip. • Pull the straps as tight as possible - The buckles are a bit tricky to manipulate in order to shorten the straps but that's to make them strong when driving.Perservere. I was away for a year,so it was like moving house to come home. I had two cat baskets taking up half the rear seat and a person in my passenger seat and still got a years' worth of stuff in the car and the bag with plenty of room to spare in the bag. I drove from Manchester over the M60/62 via the Pennines in a dreadful rainstorm with many hills and there was no drag and no leakage. You won't regret buying this and you can never overestimate how much it holds. I laid it out on a KS bed first to check how much it would fit.Then I took a photo of everything in place and recreated it once the empty bag was on the car. We have a people-carrier sized car and the 21cuft bag fits easily. The roof of the car is 74" and the bag is 52" long. You definitely need a step-stool or a taller person's help if you're only 5'4" like me. It took us about 40 mins to get it on and packed and strapped down,in the rain and at night (Thankfully the monsoon started after it was zipped up). Next time will be quicker because we have done it before. Highly recommended.

Absolute crap straps threading after one use and the idea of pull rubbers off and clip under is ridiculous maybe good in summer it's been raining now inside car is ruined ceiling soaking as well obviously rubber wasn't sealed properly in that area stupid idea will be sending the invoice for bill to fix
