This is a nice bag but it's not great. I no longer use it for the gym because the side pockets are flawed by only having one zipper and if not fully zipped shut things fall out the side and you lose them. If the sides had two zippers you can reach down the center and the sides are still zipped correcting this problem.

I now use it as a clothing bag for travel and don't store anything of value in the side pockets.

Otherwise it's constructed well and lightweight.
