It looks very sturdy and like it will last. The only negative is that it falls too low on my back and hits the seat of the motorcycle when I ride. But it's not a deal breaker for me.

For its price and as a bag that you take to the gym (but also elsewhere), it is perfect. Very durable with quality materials (you can squeeze in a ball and shoes and it won't get damaged). The only downside is the cords it has for the back (which are not comfortable) and their length cannot be adjusted
