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.
Perfectly fits my office laptop bag
Used for 3 to 6 months
Perfectly fits my 15 inch laptop bag.The bag sits snugly in the side of my bike.Perfect for someone venturing out on the bike in this monsoon.
Decent pannier bags
Used for 2 to 8 weeks
Been lucky enough to not have tested these in the rain, but they are easy to use and have decent capacity. The finishing on the rivets inside the bag is a bit rough and could scratch laptops etc. if not protected.

The strap to stop the bags from swinging is Velcro. The straps are slightly fiddly to get to and are a little too short to reach round both parts of my b'twin pannier rack.

Overall, I'm happy with the bags.
Bang for your buck
Used for 2 to 8 weeks
There's not a lot out there to compete at this price point. Make no mistake, Ortleib's or Overbaord's these are not, but they are waterproof and sensible in terms of their rack fittings, and they are a LOT cheaper. Got them for a cycle touring fortnight away, and they were just the job. If I were going further and longer, or using for a daily commute, then I might consider something more durable and robust. As they are - good value for money and sensible compromise on cost v quality.
Not waterproof
Used for 3 to 6 months
I bought 2 of these bags to go on my bike to commute, I have had them 2 months and one of the bags has a few small holes in it, they seem to wear quickly. They are also not waterproof, more water resistant. They can handle very light rain, however, I have needed to be out in heavy rain and they do not cope at all, all my kit was soaking wet including my work stuff which includes papers and a laptop (oops). They are a great size for me and just what I needed, however, I feel they would need replacing after a year and I am looking at something else.
Nice pannier bag, but not very strong
Used for 1 week or less
I bought this pannier bag 4 days ago and have used it for 2 days only and unfortunately there is already a tear in the bottom of the bag.

I have only been using it to commute to work and not carrying many things, but will unfortunately now have to return the product. It's disappointing because I like the design and the size of the bag, but I didn't realise at the time of purchase that the base was so thin, otherwise I would have thought twice about buying it.
Great Product For The Price
Used for 1 week or less
I bought these a week or so ago for a lengthy bike ride. I'd read a few reviews and some were not very complementary. However I thought that for the price in comparison to big brands they had to be worth a try.

In use I found the bags easy to fit and waterproof in light rain (not tested in really heavy rain). They were secure and stayed put on the roughest of tracks. As they are quite compact they didn't interfere with my pedaling. I opted for the bright fluorescent yellow option to increase visibility from the side and that certainly worked!
Not fit for wet weather
Used for 2 to 8 weeks
I bought these (along with many other Btwin products) to kit my bike out for a 2 month cycle through patagonia. I'm not a regular tourer so didn't want to spend hundreds on famous German brands. However, high in the Argentine mountains we got rained on and all my gear within the panniers, including my down jacket and sleeping bag, were saturated. It made for a very unpleasant and extremely cold night. I thought I might have secured them incorrectly, so tried different methods, but every time it rained (and it rained a lot) my gear got wet and each pannier had a puddle at the bottom. I eventually lined them with bin bags which kept my clothes dry, but still meant there was a puddle I had to empty at the bottom.

Maybe they are splash proof, but they are certainly not waterproof, or watertight as claimed. In fact a simple test of filling them with water will prove this! I would also second others' remarks about the useless top strap. Very disappointed. I ended up ditching them in Chile, save me lugging them back to England.

Recommended for nipping the local shops, but not long distance in wet conditions.

Hello Lewis,

I am very sorry that the product did not do the intended job in stopping your luggage getting wet while out touring the continent. I will forward your detailed review to our product manager to review the product itself.
