Review: Awesome roof rack bag - 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. Review: Waterproof and compact to store - 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. ## Features - The HandiHoldall 400 Litres is a premium quality waterproof soft roof box that offers extra luggage space for family road trips, weekend holidays and camping adventures; the huge internal compartment offers 400 litres of additional space, capable of containing 2 x 95L or 135L HandiDuffels inside - When fully loaded, the HandiHoldall 400 dimensions are 110cm x 81cm x 41cm; unlike traditional roof boxes the HandiHoldall takes up little to no storage space when not in use; simply remove the glass fibre poles and roll the bag up; it effortlessly folds down to a compact size of 59cm x 17cm x 17cm, for easy storage in the boot of your vehicle (carrying case included) - 4 strong fiberglass poles are inserted into the base of the HandiHoldall 400 to give it a solid flat bottom, much like a ridged top box; the HandiHoldall is designed for use with traditional roof bars or roof racks and a specially designed set of straps is included for this - The HandiHoldall 400 is made from a polyester Tarpaulin and laminated with a PVC coating making it lightweight, heavy-duty and waterproof; each seam is electronically welded using intense heat and pressure, ensuring a fully waterproof seal; the storm flap protects the zipper and your belongings from dirt, rain, sleet, and snow during travel - The HandiHoldall 400 comes with the Roof Bar Fitting Kit, making it easy to install on any standard car and SUV roof rack within minutes; the zippers on the HandiHoldall are lockable, ensuring that your possessions remain safe whilst you’re away from your vehicle; The HandiHoldall is also compatible with the HandiRack Inflatable Roof Rack by HandiWorld ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CZHW2P6 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 10,275 in Automotive ( See Top 100 in Automotive ) 27 in Roof Boxes | | Brand | HandiWorld | | Brand Name | HandiWorld | | Closure Type | Zipper | | Colour | Black | | Customer Reviews | 4.2 out of 5 stars 241 Reviews | | Folded size | 59 cm (l) x 17 cm (w) x 17 cm (h) | | Global Trade Identification Number | 05060158520398 | | Included Components | Glass fibre support poles, Instruction leaflet, Roof Bar Fitting Kit, Storage bag | | Item Dimensions L x W x H | 59L x 17W x 17H centimetres | | Item Type Name | HandiHoldall 400 Litres - waterproof easy to store foldable roof box | | Item Volume | 400 Litres | | Item Weight | 8.82 Pounds | | Item weight | 8.82 Pounds | | Manufacturer | HandiWorld Ltd | | Manufacturer Part Number | HHOLDALLWP400 | | Manufacturer Warranty Description | One year warranty against manufacturing defect | | Material | Polyester with PVC coating | | Material Type | Polyester with PVC coating | | Model Number | HHOLDALLWP400 | | Mounting Type | Roof Mount | | Number of Items | 1 | | Product dimensions | 59L x 17W x 17H centimetres | | Shell Type | Soft | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Brand:** HandiWorld - **Material:** Polyester with PVC coating - **Product dimensions:** 59L x 17W x 17H centimetres - **Colour:** Black - **Item weight:** 8.82 Pounds ## Images ![HandiHoldall XL 400L Waterproof Roof Bag / Top Box (Black) – Cargo Carrier with Foldable Solid Base - Image 1](https://m.media-amazon.com/images/I/81tYz9ZUFQL.jpg) ## Questions & Answers **Q: What are the internal diameter size?** A: The bag is rectangular rather than round, and the internal dimensions are almost the same as the external dimensions, as the bag wall thickness is negligible. **Q: Do you need the inflatable things if i have roof bars?** A: You don’t if you can position your roof bars. Ours are fixed position so could only tie on to one roof bar. However using the roof bars & the inflatable supports spreads the weight really evenly. I suggest both if you can !! **Q: what are the dimensions of this when it is unpacked? Thanks** A: The dimensions are listed on a picture on the Amazon advert **Q: How to thread short strap into the tooth holder/hole? Strap too thick.** A: The short straps pass through 1 of the 3 webbing mounting points on the underside of the bag in each 4 corners of the bag. You need to offer the bag to the roof bars and choose the point that aligns with each bar. This system provides adjustment depending on the pitch of your roof bars when you fitted them. The short straps have a grippy rubber side to prevent slipping on the roof bars when fitted, you need to depress the metal cam to make the gap wide enough to pass the strap end through. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome roof rack bag *by S***E on 12 August 2022* 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. ### ⭐⭐⭐⭐⭐ Waterproof and compact to store *by C***T on 1 November 2019* 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. ### ⭐⭐⭐⭐ The straps let it down *by M***E on 4 September 2022* 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. ## Frequently Bought Together - HandiHoldall XL 400L Waterproof Roof Bag / Top Box (Black) – Cargo Carrier with Foldable Solid Base - HandiWorld HRACK HandiRack Universal Car Roof Rack; Quick Fit Heavy-duty Roof Bars; Black, H10, W33, D146cm - HandiRack HWASP HandiRack Anti-slip Pads, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/68321464-handiholdall-xl-400l-waterproof-roof-bag-top-box-black-cargo](https://www.desertcart.jp/products/68321464-handiholdall-xl-400l-waterproof-roof-bag-top-box-black-cargo) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-24*
