| Lock | One combination lock; zip closure | [1] |

Known issues and safety
Recall check: we searched GOV.UK product safety alerts, reports and recalls (Office for Product Safety and Standards) for “roof bars” on 19 October 2026. The first page showed nothing about roof bags, boxes or racks, and we could not check the second page [2]. Check the list again before you buy.
Check your car’s maximum roof load in the handbook, and the weight of the bag and its contents. A soft bag is not a rigid box: pack heavy items low and in the middle, and check the straps after the first few miles.
Questions people ask
Is it really waterproof?
The listing says waterproof [1], but gives no rating or test. Bags with zips and straps can let water in, so line the contents with bin liners if they must stay dry.
Does it include a roof mat?
The listing says yes in one place and no in another [1]. Ask the seller.
Do I need roof bars?
BOYUJK markets the bag for cars with or without racks, but we could not verify that on a maker page. Check the instructions before use.

Our verdict
Based on the evidence, this is a budget soft roof bag with a lock and straps. The only page we could open is an ex-display listing with conflicting details, so check size, contents and load limit with the seller before buying. This is a research summary, not a test result.
