Waterproof Pannier Rack Bike Bag 20 L - 500 Black

Brilliant bags in the sense of space, waterproofing, ease of attaching to panniers, and price. Would highly recommend if you aren’t using them long term. Only issue I’ve had is the velcro wore away completely after only about 3 weeks of use, so the straps would get caught in my spokes and in the end I just had to cut them off. Great product in the short term, but not sure if they’re any good for long term use.

Just been to Holland for 4 days and used one of these panniers. Easy to use and decent quality for the money. Did not test how waterproof though as weather stayed dry. Used zip lock bags for clothes just in case. Now looking to buy another for longer trips.

Great for the money.

Good product

Great bag to bring along during rides to work or leisure. Load my 2x1.5L water bottles n some snacks. Too convenient for me to dropby decathlon n pickup items 🤭

Good quality product which do the job.

As with anything Decathlon, the bag is value for money. I used it for a few months for commuting. Kept my things dry.

But I recently found a tear near the bottom of the bag. I am going to stitch it back - but could be more durable since I don't put very heavy things inside.

I have been using the bag for shopping trips, and it's decently well made with good material. Quoted capacity is smaller than many panniers, and I can see this when filling it up - and folding the top over to close uses up vital space. However it can be used loosely clipped (provided it's not raining!) to get more groceries in, or a french bread sticking out the top!
The clipping shut takes a little getting used to with the fold/clip which isn't initially intuitive.
I haven't taken the bag out in heavy rain, but it is shower proof.
Clips nice and firm to the cycle rack, and the tightness of grip can be adjusted to suit.
One negative is that there is no shoulder strap. It would have been easy to have a strap supplied that clips into the clips already on the bag for closing it.

For the price, very satisfied with this bag - but do bear in mind the size limitations and lack of off-bike carrying strap.

Love this bag. Super easy to fit onto my bike .Useful size for carrying my gym gear or a few things from the shop . Easy to pack flat .

Clips on to (and off) racks with an adjustable screw fitting for 6-16mm horizontal bar size - so fits virtually any rack.
The bit of string operates a hook that turns 90⁰ in the vertical plane to operate a clip that hooks under the same horizontal bar to stop the bag bouncing upwards and becoming detached.
I cut a piece of closed cell foam (not water absorbent) to protect the base of the bag from damage. I added 2 rivets as another reviewer suggested to strengthen the lower velcro strap attachment to the bag. I stitched an extension to the lower velcro strap so it fixes around two of my vertical stays, not just one, to get a more secure fitting. Now a 5 star bag!
Rolling the top of the bag over 3x and clipping it will make it watertight.
