This gym bag rocks. I wanted something not to big, and this is the ticket. There is just enough room for all of my workout clothes. The shoe compartment is just big enough (i wear a size 10 1/2), so if you have a bigger shoe, I would look for another bag. Good quality, and I expect it will last me for some time to come.

I own two of these bags, and have purchased three (blue, gold, and green, respectively). I purchased one in the medium-size for the gym (blue); a medium-size for carry-on for airline travel (gold); the large/xlarge (I can't remember) I purchased for my grandmother for her swimming.

The waterproof side-pouch is my favorite feature. I use it for hiking sandals/dress shoes for travel (not quite big enough for running shoes in the med size - I wear a women's 9), and I keep toiletries and leak-ables (shampoo, etc.) in it in my gym bag.

I also like the end pouch at the other end (it is like many other duffel bags) because it is just the right size (in the med-duffel) for a TSA 3-1-1 bag for carry on. This means that all your gels and liquids are packaged up there with easy access, which makes going through security much easier. I had a little room in this pouch for a couple of other small items. In my gym bag, I keep small items I need quickly there: locker pad lock, ankle/wrist braces, etc.

The medium size is good for travel and the gym. It fits fine under the seat in front of you on the aircraft. It will fit in the overhead bins, but is too long to put in width-wise (with the end sticking out) in a smaller aircraft (maybe would fit in a bigger one, I don't know). This bag also fits well under my desk and in the gym locker.

The colors are vibrant and strong, and while I haven't had great opportunity to greatly abuse these bags yet, so far they have exhibited excellent durability.
