Not Particularly Durable
Used for 7 to 12 months
A number of adverse reviews have commented that this bag is not waterproof. I have found it sufficiently waterproof, but not very durable. I bought my bag in mid-April 2018. I have noticed that at the bottom there is an area where the waterproof coating is coming away. That might not be so terrible, but for the fact that the fabric is also fraying in the same place, and eventually will give way.

I am not sure why this has happened. The external base of the bag is never in contact with anything and cannot be subject to friction. I would not expect a stone thrown up from the road to do the damage. I only generally carry the following inside the bag:

1) Kryptonite Evolution D-lock plus cable
2) Smaller B'Twin D-lock
3) Saddle bag containing inner tube, small multi-tool and puncture repair kit
4) Small hand pump

Typical weight of the bag plus contents is rarely more than 4kg and usually less, so the bag is not being over-stressed.

The bag has functioned well and to purpose over the last nine months, but I have doubts about its durability.
Response of the brand
Dear Sir,
Thank you for the review of this bike bag. I will indeed forward this on to the Riverside team at Decathlon Cycles. I would be very keen to get a few photos to send to the Decathlon team (if you can). In the meantime, please return it to us for an exchange or a refund.

Used for 2 to 8 weeks
Bought it to cycle to work. Haven't been tested under strong rain yet. Practical, easy to install day in day out.
Good value pannier
Used for 2 to 8 weeks
Used 2 of these panniers on a cycling trip from Brighton to Paris over 3 days. They are strong & easy to open/close when stopping. Good fixing system allows them to be taken off easily, and useful carrying handle. Can't comment on their waterproofing as it was 30°C with not a cloud in sight. Would recommend this pannier as good value.
