Review: Definitely a good buy - 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
Review: Must buy for camping! - Brilliant roof bag, cannot recommend enough! We use this for camping and have used twice so far and it has been brilliant! Carries a lot and safe and secure. Comes with an anti slip mat too. We have a Golf R which has glued on door seals so we couldn’t hook the straps under the seals, so we had to improvise and purchased extra straps so they go all the way through the car. Works great. I would encourage anyone to buy this :)

### ⭐⭐⭐⭐ Works well but you need to allow plenty of time to install and secure it.
*by S***R on 10 September 2025*

We just completed our first trip to Europe with this roof bag. Positives: * The bag construction seems strong and had space for a lot of our stuff. * It remained waterproof despite driving through very heavy rain for most of a day. * The 10 straps gives plenty of confidence that it will stay secure, even at motorway speeds. * The non-slip mat remained in place with no issues. * It remained solidly secured between my roof bars through-out the trip. I only had to stop once to secure a flapping strap end that had come loose. * I didn't find it added much noise over what my roof bars already add. Negatives: * The supplied lock was really flimsy and never worked, so I bought a key and padlock to secure the bag. * It takes longer than you would expect to fit the bag, fill it and secure it. By the end of the trip, I had it down to about 40mins to install and secure. * Tightening the straps takes effort and is fiddly. * Despite using rolled blankets inside the bag to give some shape to it, it certainly hurts the MPG, especially at motorway speeds.
