Bright colour, waterproof, decent size, easy to fit

Let's get this out of the way from the start -- when I bought this, I thought I was getting a pair of panniers. I mean, who would want a single pannier? It never even occurred to me that anybody would sell panniers singly. That makes as much sense to me as selling half a pair of trousers. So my review is kind of tainted by the fact that I'm going to have to spend twice as much money as I thought. A pair of these panniers would be great value, if sold for the price I paid for one. For twice that price, I'm not entirely convinced.Leaving aside the price, it's a splendid item. The material is a kind of heavy, rubberised plastic, that looks like it will be robust and waterproof. I haven't tried it in a downpour yet, but I can't see any place the bag would let water in, if it's closed properly. The capacity is remarkable, although I think it would be hard to use the full capacity if you needed the pannier to be waterproof -- it would be difficult to fold the top over enough times to create a proper seal.The pannier clips easily and securely onto my rack. There are three, rigid points of attachment, all adjustable, so it doesn't move at all when in place. However, the lower attachment point is on an vertical strut of my rack, not a horizontal one. This means that the assembly relies entirely on the top clips to prevent the whole thing bouncing off when riding over bumps. I don't think it will come off -- it hasn't so far -- but for security I prefer the attachment arrangement of my old panniers, which have a clip near the rear axle that completely prevents the bag moving upwards.An interesting touch is that there is a cable that allows both the top clips to be opened at the same time, rather than one with each hand. I don't really understand what this is for, unless it's to allow the pannier to be removed one-handed. I can't think of any circumstances in which I would need to do that, but I can see why some people might. Or maybe this one-handed release is for some other purpose, that I haven't fathomed yet. All the clips are large, and would be easy to operate with gloved hands in the cold.At the bottom of the bag is a little flap labeled "light clip". I can see how it would be easy to clip a rear light on there, and why that would be convenient. However, every rear light I've ever used would end up facing to the side, not the rear, if clipped into that location. So I can't think of any use for it.There's an external zipped pocket which can be opened when the main bag is closed, and I can certainly think of uses for that. A shoulder strap is included, and it seems to be soundly constructed, although I haven't used it.All in all, this is probably the best pannier I've ever used, despite the slight flaws. It's just, way, way too expensive. There are plenty of pairs of panniers for sale, on Amazon and elsewhere, no more expensive than this single pannier. The fact that it's easy to remove is no doubt an advantage if you think of it as a kind of bicycle-mounted rucksack, and plan to carry it about. However, if you plan to leave it installed all the time, panniers this expensive would be a great loss if they were stolen, and stealing them would be easy unless they were somehow chained down.If I needed to carry a laptop computer and a sandwich to work, I can really see this pannier being a good choice for using like a rucksack. For permanent installation, though, it's just too expensive and too steal-able to be a compelling purchase.

I like the size and quality as well as the ease of installation and operation.I would definitely recommend.

Bought the pair.Can't recommend highly enough. Got them for my shopping, made such a difference to carrying my weekly shop on my bike.Fits loads in, fully waterproof. So handy to have.

Used these in bike packing and yes they are waterproof.material got softer over time which I liked.easily attached to my rack and very secure .not so keen on the inside pocket as quite a tight fit putting anything in them so I don't use.but happy bunny with my purchase
