HandiHoldall XL 400L Waterproof Roof Bag / Top Box (Black) – Cargo Carrier with Foldable Solid Base

There is not really a good flattering photo of the bag when fitted correctly as the straps press down on the bag and make it look how it does in my image, the bag was twice as fast to I stall the second time as I knew exactly what to do, you get 4 small straps one for each corner of your roof bars and 4 long straps one for each corner of the top of the bag that wrap around the ends of your roof bars, the straps are made of a very tough material that is grippy on one side and the clasps are metal so should last, it's very easy to throw on the roof and get centre than clasp each corner, I put all 4 clasps onto the bars loose them step back and adjust left or right until centre then tighten up the straps, the bag easily takes 6 X full large bags for life + covers coats etc there is tonnes of tmroom it's really fantastic, I have used once in very windy conditions and obviously it didn't budge, definitely remember to tuck in any loose straps as they will tap on the roof and be very annoying as I found out the first use, I highly recommend this product.

This product is fantastic stood upto torrential rain heading off on holiday no water ingress on a five hour trip. Fits in three cases and a large canvass shopping bag. Really recommend this product

The product as a whole, isn't great. The bottom straps are really fiddly and the side straps are too short and put too much strain on the stitching. You'll also have to get your super glue out to properly stick the ends of the poles on, otherwise they'll come off every time you use it.Take away the negatives, however, and the the bag itself is pretty good. It's essentially a massive dry bag. I ended up getting some 4m ratchet straps, that were perfect for wrapping around roof bars and going all the way over the bag, removing the pulling strain from the bag loops. This worked a treat and turned a pretty poor product into something that is pretty great. Shame it doesn't come with better strapping. If it did, it would be a great buy. As it stands, you need to think about additional cost for better straps.Pros:- Bag keeps everything dry, just make sure you face the storm flaps into the wind.- Packs away easily and to a small size, you'll be able to throw it any cupboard.- Good size. You can get a lot in it. It was perfect for a camping trip.Cons:- Straps are not suitable for the bag. Useful for something else, maybe.- Ends of the poles fall off easily and need additional gluing.- Pole slots aren't designed very well and do tend to slip out. Haven't noticed this being much of a problem though, especially if you pack well and have other supports to give the bag rigidity on the roof.Other things to note:- You do have to fill it when using it, it's no good putting a small amount in it.- The bag is not the thickest material and gets soft in the sun, so you'll need to be careful when putting it on the roof. Once up there it's fine and can take the wind without a problem.All said, I would recommend the bag when using 2x4m ratchet straps. It's great if you haven't got space to store a rigid roof box. Fitted this to a Mini Cooper and it was a perfect size.

Product so bad. Not wasting time on it.

Good quality bag, sturdy zips and velcro used to keep rain out. We had rain on our drive to Wales. NO LEAKS.We drove 70+ miles an hour no issue. Not windy day.Install aided with steps at home, but stood in door well at camp site for return. I'm 6ft 1 though so shorter people may need help.The ties are good quality, best to have one person pull down and the other one work the grip mechanism.Packed away really small, but we used at the camp site to store (inside our tent) our kids clothes.We bought metal rails for about £100 and this to keep cost of camping down, happy, and would recommend to others.

I was really impressed with this and it is cavernous as other reviewers have pointed out. It dealt with very heavy rainfall no problem and was easy to pop onto the roof bars.The frustration was twofold. Firstly when I was fastening to the bars as per the instructions, the strapping looked like it was coming away from the bag when I pulled tight (not over tight). I think that is a case of trusting the straps maybe (possibly they don't need to be too tight) and I did add ratchet straps for complete piece of mind. Secondly, when I removed the storm flap, the velcro just peeled off the main bag as the glue had presumably failed. Without being able to seal the storm flap properly I had to return.I might have been unlucky if no one else has had this problem so worthy of consideration as overall the bag seems to be pretty good.

Waterproof. Great capacity. Very useful. Tricky first time to attach but will be easier 2nd. I added extra bungee ropes to give me peace of mind. Travelled 70mph motorway and it stayed on! Haha. 400l version hold alot. Very happy with item. 400l is a hard waterproof rubbery style and family member bought 320l and it was a tough fabric design. Zips stuff. I filled before attaching so I didn't need to stretch. Handy to have a foot stool to reach when emptying/filling. Some places say it hold 50kg but mine says 80kg on it. Took heavier camping items in the boot and bigger bulky sleeping bags etc on top.

Fab item - we use it to put lighter camping stuff in (airbeds, sleeping bags etc) and it holds a lot! It was definitely tested last weekend as we set off in torrential rain that continued for the whole journey. All items inside were nice and dry when we arrived though.When not in use it’s super compact - which is why we bought as we don’t have space to store a box.The reinforced bars mean no sagging and you can attach to your roof bars properly.
