Premium Thule bars or budget roof bag: which is the smarter buy?

Display

There is no screen or display on either product, so this category does not apply in the usual sense. In practical terms, the closest equivalent is how easy each product is to understand and use day to day. The Sailnovo wins here for simplicity: it is a soft roof bag that comes with 6 reinforced straps and 6 door hooks, so the setup is straightforward for occasional use. The Thule 710600 is more complex because it is a roof rack base system, but that complexity buys you a more robust and repeatable fit. Winner: Sailnovo for quick, simple usability; Thule if you want a more engineered system.

Performance

Performance here means how well each product does its job on UK roads, especially at motorway speeds, in wind, and in wet weather. The Thule 710600 wins decisively because a roof rack is the foundation for stable load carrying. It is designed to hold cargo boxes, bike carriers, ski racks, and other accessories with better rigidity and less movement. The Sailnovo bag can carry a lot of soft luggage at 20 cubic feet, but soft roof bags are inherently more affected by wind drag, weather exposure, and packing shape. On long M1, M6, or A-road journeys, the Thule system is the stronger performer.

Build quality and design

This is where the gap becomes clear. Thule has a strong reputation for premium materials, precise fit, and long-term durability, and the 4.6/5 rating from 1,462 reviews supports that. The 710600 roof rack is a purpose-built product intended to stay secure and integrate cleanly with your vehicle. The Sailnovo also scores well at 4.5/5 from 3,239 reviews, which suggests many buyers are satisfied, but it is still a soft roof bag with a more temporary design. It is more vulnerable to abrasion, weathering, and user error than a metal roof rack system. Winner: Thule.

Battery life

Neither product uses a battery, so this category is not relevant. If you are comparing them by convenience instead, the Sailnovo has the advantage of being packable and storable when not in use, while the Thule is a fitted system that may remain on the car. However, if you leave the roof rack on year-round, you may accept a small fuel economy penalty from extra drag. Winner: tie, because battery life does not apply.

Price and value for money

The Sailnovo is the clear winner on upfront cost. At £66.49, it is £54 cheaper than the Thule at £120.49, which is a meaningful saving for families who only need extra space a few times a year. It also includes 6 reinforced straps and 6 door hooks, so you get a complete budget cargo solution in one box. But value is not just the purchase price. The Thule may cost more, yet it is likely to last longer, fit better, and provide a more secure base for future accessories. If you plan to use roof storage regularly, the Thule’s higher price can be justified over time. Winner: Sailnovo for budget buyers; Thule for long-term value.

Game library/features

This category does not apply literally, but in accessory terms it is best read as versatility and feature set. The Thule 710600 wins because a roof rack opens up a wider ecosystem: roof boxes, bike carriers, ski attachments, and other Thule-compatible accessories. That makes it much more versatile for changing needs across the year, from summer holidays to winter sports. The Sailnovo’s feature set is narrower: it is mainly a large, foldable cargo bag for soft luggage. It does that job well, but it does not create the same platform for future upgrades. Winner: Thule.

Overall user experience

For everyday user experience, the best choice depends on how often you will use it and how much hassle you can tolerate. The Sailnovo is easier to justify if you need occasional extra space, want to keep costs down, and prefer something you can store in the boot when not in use. It is especially appealing for renters, drivers without roof bars, or anyone who does not want a permanent setup. The Thule 710600 is the better experience for people who want a safer, cleaner, more confidence-inspiring solution for repeated use. It is the sort of product that feels more secure in bad UK weather and is more likely to integrate neatly with your car and future accessories. For insurance-minded drivers, a properly fitted Thule-style roof system may also feel more reassuring than a soft bag strapped through doors, though you should always check your policy and fitment carefully.

Overall summary: if you want the cheapest practical way to add luggage space, the Sailnovo is excellent value and hard to ignore. If you want the better-built, more versatile, more secure solution for regular use, the Thule 710600 is the superior product. The Thule wins the head-to-head on quality, performance, and long-term ownership, while the Sailnovo wins on price and convenience.
