Rymopuey Roof Bag: 20 Cubic Feet of Waterproof, No-Rrack Installation Car Roof Storage
Product description
What it is and what it solves
The Rymopuey Roof Bag is a weatherproof, foldable roof cargo carrier designed to add significant storage space to a vehicle without needing a roof rack. With a high-density PVC double waterproof coating and a two-way zip plus Velcro flap, it aims to keep luggage dry and clean even in challenging conditions. This can help reduce crowding inside the cabin on family trips or weekend getaways, making it a practical option for those who occasionally need extra capacity without committing to a permanent roof rack.
How it’s laid out for use

On the road, the bag sits on an anti-slip mat that helps minimise movement and protects the roof finish. It’s supplied with multiple straps and door hooks to secure it, and it’s advertised as compatible with cars both with and without racks, cross bars, or baskets. The installation is described as quick and tool-free, which is useful for spontaneous trips or short notice packing.
What stands out on paper
A key draw is the claimed 20 cubic feet of storage, enough to accommodate suitcases, tents and sleeping gear for a group, while keeping the interior free for passengers. The dual protection system (zip plus Velcro) is intended to guard against dampness, dust, and wind-driven rain as you travel.



What may not wow you
While the packaging highlights its versatility for vehicles without roof racks, real-world fit can vary depending on roof shape, edge contours, and luggage dimensions. The claim of “all vehicle compatibility” is optimistic, some small or unusually shaped roofs may require extra care to secure correctly. If you’re chasing a premium hard-shell feel or integrated roof rack aesthetics, this soft bag will not replicate that look or rigidity.
Who it’s for

This roof bag is well-suited for families or travellers who occasionally need extra space and prefer a removable, storage-only solution. It fits if you want a flexible option for weekend trips, beach days, or camping jaunts where extra luggage capacity is beneficial but you don’t want a permanent rack setup.
Who it isn’t ideal for
If you frequently travel with very bulky or heavy loads, or you prioritise a rigid, built-in feel with no movement whatsoever at high speeds on rough roads, a hard roof box with a dedicated base may be preferable.



What to check before you buy
- Confirm your car roof’s compatibility with the bag’s dimensions and the maximum load it can carry (inside the bag’s stated capacity).
- Ensure you understand how the anti-slip mat behaves on your roof material and whether any weatherproofing features are sufficient for your typical conditions.
- Consider how you’ll store the bag when not in use, folding into a drawstring bag is convenient, but you’ll want a dry, accessible storage spot.
- Evaluate how often you’ll deploy the bag and whether tool-free setup aligns with your usual packing routine.
Practical usage notes

Imagine loading a week’s worth of camping gear for a family trip, with the inside cabin still comfortable for passengers. On a windy highway or bumpy back road, the anti-slip mat and reinforced straps are meant to keep everything steady. If you prioritise straightforward, no-fuss setup, this bag offers a practical balance between capacity and ease of use.
A comparison in mind
If you’re weighing soft storage versus a hard-shell alternative, soft roof bags tend to be lighter and easier to stow when not in use, but they may require more attention to securing loads and weatherproofing depending on conditions. For those seeking versatility for occasional needs rather than daily cargo, this option can provide good value and flexibility.



Decision time
Is it worth it?
Worth considering if you need supplementary cargo space without a permanent roof rack and you want a straightforward, foldable option that works with or without existing racks. It may not be ideal if you require maximum rigidity or plan to run frequent high-speed trips with very heavy luggage.
FAQ
- How much storage does it actually hold? It’s described as 20 cubic feet of space, suitable for multiple large bags or camping gear.
- Do you need a roof rack to use it? It’s marketed as usable with or without racks, but installation hinges on securing it safely with included straps and hooks.
- How weatherproof is it in heavy rain or snow? The product highlights a double waterproof coating and a two-way waterproof zip for protection, but no substitute for careful packing and weather awareness.
Final thoughts
If you’re after extra cargo space for family trips or outdoor gear, and you want a lightweight, removable solution that folds away when not needed, this Rymopuey roof bag offers a pragmatic approach. It’s not a high-end rigidity solution, but it brings flexibility and value for its intended use.
What to know
If you prioritise a long-term, high-load, rigid transport solution, you may want to explore alternatives with hard shells or dedicated rack systems. For occasional, convenience-driven needs, this bag aligns with a practical, value-focused buying decision.
