This is big and works great for swim meets with more than 1 swimmer.  I have 2 swimmers and they each have about 4 events each meet.  I need to bring about 6-8 towels each meet with the boys' change of clothes, and swim jackets with some room to spare.  They have pockets on the outside.  I put the goggles and swim caps there.  There is a wet compartment for the wet clothes.  I like the wheels and the telescopic handles.
