Review: Perfect for Road Trips - A Must-Have for Extra Luggage Space - I recently took the Marretoo Car Roof Bag on a long road trip, and I have to say, it made the journey so much easier! We were heading off for a week-long camping trip and needed extra space for all our gear. This roof bag provided 21 cubic feet of storage, which was more than enough to fit everything we needed without overcrowding the car. I was able to pack up camping chairs, a tent, sleeping bags, and more—essentially everything we needed for the trip—and still had room to spare. One of the things I really appreciated was how well the bag performed in less-than-ideal weather. It rained during part of our trip, but the bag kept everything dry and secure. The material feels tough and durable, and the zippers were easy to operate, even with gloves on. The anti-slip mat that came with it was also super helpful in keeping the bag stable on the roof, preventing any movement while driving. I also found the installation to be surprisingly easy. We have a roof rack, and it took just a few minutes to strap the bag down securely. It stayed in place the whole trip without any shifting, and I didn’t have to worry about it at all. When we weren’t using it, the bag folds up neatly, making storage a breeze, which was a bonus. However, I did notice one small thing—because the bag is on the larger side, it can look a bit bulky when it’s not fully packed. If you only have a few things to carry, it might seem a little excessive. Also, if you’re loading it onto a higher car, you might need a little extra reach to get it securely placed, but once it’s on, it’s all good. In all, I’m really happy with the Marretoo Car Roof Bag. It made our trip so much smoother by freeing up space inside the car, and knowing everything was protected from the weather was a huge relief. If you’re looking for a way to bring extra luggage along on a road trip or vacation, I highly recommend this bag. It’s durable, waterproof, and super easy to use!
Review: Fantastic bit of kit - So i planned the holiday was 300 miles away from home I had a sneaky feeling the luggage tent ect wasn’t going to fit. I was absolutely correct after a lot of research I came across this bag I didn’t have roof bars so it seemed perfect. I can tell you now I have done over 600 miles with this roof bag on and it did not move an inch. It stayed still and sturdy on the motorways. It is really good quality and brilliant value for money. We did have some rain but it seemed to keep everything dry. Really straight forward to put on. We managed to get so much in there and now won’t be going camping without it. I highly recommend.
