I'd been looking for a not-go-giant bag for adult league and really glad I chose this medium bag. I wear 14" shins and medium to large pants/shoulders/etc. and this bag fits everything (plus multiple jerseys) with room to spare. Construction seems very high quality and holds its shape well, this should last many many years to come. If you're a taller/bigger player or want the second side pocket then the larger bag may be for you, but this is perfect for those that want something a bit more compact.
