My old gym bag was about the same size, maybe a little smaller, but it lasted through *years* of rough use.

The material of this bag is much weaker compared to my older bag.  Subjected to substantially similar use, this bag didn't perform nearly as well because, 1) the *first* time I took it to the gym, the base seam of the zippable external pocket ripped open; and 2) after nine months, the material at the base of the carrying strap has begun to tear on one side. Given it has served for nine months, it gets two stars instead of one.

In short, I can't recommend it.  I've had much better bags than this one for about the same amount of money and expect I will again soon. I will be buying a replacement in the near term and I will not be considering a New Balance brand bag.
