From the Reds website:
Guests are welcome to bring SOFT-SIDED coolers into Great American Ball Park provided the coolers' dimensions do not exceed the 16" x 16" x 8" inch Major League Baseball size requirement. HARD-SIDED coolers of any size are prohibited from entering the ballpark. Coolers and all carry-in items are always subject to inspection by Reds personnel prior to entrance to the ballpark or at any time while inside the ballpark.
