Very good purchase

Used for 3 years, hasn't moved since, still as practical, good value for money

This is what I was looking for!

Hello, let me just briefly describe that I have been actively riding MTB bikes for 8 years, of which I have been riding a Trail bike for 3 years, covering approximately 8,000 km per year, riding on terrain from asphalt to the Beskid trails. Since I've been hiking in the mountains, I've been testing various options for carrying water and equipment until I finally decided on the above-mentioned waist bag. Before I bought it, I was trying on a fanny pack from a well-known manufacturer for PLN 400. I decided to buy the Rockrider fanny pack because it is no different from the ones for PLN 400 or PLN 700 😉 before purchasing, I also read the user opinions below, to which I will refer. While riding on the trails, I was terribly irritated by the fact that each backpack bounced on the backpack during faster rides, creating a sporty discomfort for me, not to mention a wet back 😂😂 but to the end, after a few fittings to properly position the bag on my back, I achieved such comfort that I completely ignored it. I forgot. This bag adheres well to the body, so it does not come off or jump on bumps or light jumps. Its size is optimal, I can carry just over 1 liter of water, a bicycle multitool, a pump, a phone, a scarf, bars, a thin hat (on colder days), keys, a minimalist first aid kit, 2 x lamps and a few other gadgets 🚬. In my opinion, it allows you to take the optimal amount of things for cycling along mountain trails. It is known that if someone plans to take a jacket or, for example, inner tubes, there may not be enough space, but I do not consider it a disadvantage because the waist bag is supposed to be more handy than a backpack. As for the quality of workmanship and ergonomics, it is at the level of leading brands, the only thing I could complain about is that you need to develop the habit of putting the tube from the water bottle in one place in the same place, because the socket with a magnet forces us to be somewhat precise (the use may stronger magnets would allow for greater tolerance). I hope my opinion will be helpful for people who are hesitant.

The only downside is that after returning from an outing where there was mud, it is not necessarily easy to wash. I put it in the washing machine but had trouble getting it to dry properly.
