SHINYEVER Waterproof Bike Pannier Bag 22L，Multifunction Bicycle Rear Seat Bag Laptop Backpack Motor Trunk Bag Luggage Bag，3-in-1 Bike Rack Bag, Backpack, Cycle Carrier

I've been looking for the perfect bag for my commute and hopefully this is it!As a backpack - this works well, has lots of space inside and the straps are comfortable. Of course with the pannier clips behind the shoulder blades it isn't as comfy as a conventional backpack, but it's not overly noticeable and with time you'll likely become accustomed. The internal laptop bag is a good size and also slightly padded to better protect your goods. It would have been nice to have another internal pocket or separator of some kind.As a pannier bag - the clip is very convenient. Depending on the shape of your rack, it is easy to affix and the strap at the bottom keeps it secure. The clip 'locks' on and off when you lift the handle. To improve, I would have recommended the plastic spacers were made of rubber, as they have a tendency to slide side to side while riding, but only in extremes.The shoulder strap supplied has good quality buckles and seems robust.Overall the quality of materials used is impressive. The thick material seems waterproof enough for the wettest commute. That said - the quality of the finishing at the seams is lacking in some areas (as photos). This was.mostky easy to tidy up, but I'm a little concerned the bag will not have a long life due to this. I even found an additional offcut of mis-sewn material inside. The mesh used on the side pockets and helmet holder is stretchy but very thin and I'm very conscious of tearing it when putting bottles in the side.Overall - I'm really impressed with the bag for the price. It is sturdy, made of thick, strong material with high quality buckles and straps. It is easy to use as a pannier bag and convenient to switch to a backpack afterward. Perfect for commuting, bike-packing or days out. I would recommend the bag to any cyclist, especially the commuter.(NB the light in the photos is my own)

Does everything I need. Lovely little bag and well made. Recommend.

Bag arrived and initially looked good, but I soon realised that the top of the bag had 2 female buckles instead of a male and female buckle so its physically impossible to close the bag. Both buckles were sewn to the strap too so I was unable to replace it with a male buckle from somewhere else on the bag. Not ideal when I needed the bag for a bike trip. Evidently the bag didn't go through any quality control as being able to close a bag would be quite hard to miss.

I've had this bag a couple of months now and it's still as good as when I first got it. It's a good size, I can fit my laptop, lunch and change of clothes in it (just). I really like the fact that it has the option to carry it as a back pack or as a side bag or just carry it from the fastening loop. 100% waterproof.
