Excellent bag, it can fit a lot of things and it is completely waterproof if you close it correctly and don't overdo it. It ties perfectly with 4 very close tentacles if you have the ability to tie it to the saddle in the position of the second one even better. I am referring to the 60lt bag where they are the same

Very good for its price, I don't know about any waterproof certification, but even in rain that I have experienced, it didn't get wet. It has fallen off the motorcycle and from the motorcycle with quite a few kilometers and nothing happened to it. It doesn't have many compartments, it's just a single compartment bag, but with very good material and very nice straps for tightening and fastening. It is one of those products that you buy because you want something reliable and you pay some money once and that's it.

It fit things for a lightweight week-long camping trip with a scooter in Crete in the summer (sleeping pad, sleeping bag, changes of clothes, canned food, tools, small items) and it didn't complain. If you don't pack camping gear, it can fit a few days' worth of clothes for two people. Very good bag even as the only choice for travel luggage on a motorcycle. If I could travel 1000 kilometers with this bag using a 100cc scooter, any motorcycle won't have a problem if you use your brain, two straps, and have the desire for rides.

The only disadvantage of the bags is that they sit nicely in the passenger's position. If you want a passenger, get saddlebags/suitcases or at least tie it tightly to a rear rack. The advantage of the bags is that they cost 60 euros for 40 liters, which are durable, fully usable, and will suffice for one person, maybe two if you don't live in the mountains. I think there is a similar bag available in 60 liters, so check it out.

I haven't used it yet on a motorcycle trip, but friends who travel frequently had recommended it to me and use it constantly. I am sure it is the best.

Excellent bag tested in all kinds of weather conditions without suffering any damage itself or to its contents. I use it as an auxiliary for long trips or as the main bag for short excursions.

Very good quality bag, very convenient either for attaching to the saddle or in a suitcase with good rings and it seems like it won't have a problem with rain. I would like it to have a pocket.
