This tidy little bag is quite an improvement over others I've purchased over the years. It's quite nice that it will fit in shallow lockers, and access to the pockets is effortless. The material is very good and a good balance between being thick and durable versus too heavy. The only thing that gives me pause is the shoe pocket. It is quite shallow, so only smaller shoes will fit, but more significantly the zipper opens at the bottom corner of the bag which makes it awkward to unzip and zip up, and you need to lift the flap while inserting shoes. The medium bag has the zipper(s) to my liking where they are on the side and the flap opens with gravity.

Large enough to fit a squat bar pad in the main pocket. The single side pocket is not quite large enough for a regular towel, but the second shoe pocket is large enough. The 2 shoe pockets are not connected so the towel stays clean away from my shoes. Enough room for a shaving bag and a change of clothes.
