After an experience with a €20 running bag, where the two water bottles started leaking and at the end of each workout, my shorts were soaked, I bought this one.
Conclusion...

Anyone who is into running and wants to wear a bag that doesn't move from its position, comfortably fits their phone, keys, and water bottles, and is of good quality, simply buys this one.
At €40 on Black Friday, I am extremely satisfied.
I know it may seem expensive, but it's worth it...
