All Beato bags come with the Professional Drum Shop logo. Bags are sized by the size of the drum shell. For example, if your snare drum is a 6 1/2" x 14", the 6 1/2x14 snare case would fit. If you have a floor tom that is 16" across by 14" deep, the size of the case would be a 14x16 floor tom. These measurements should be taken without any hardware on the drums (rims, lugs, etc). For example, if you measure depth of a 14"x22" Ludwig bass drum that has the wood hoops on either side of the drum, the bass drum will appear to be 16 3/4", not 14". However, the proper case is a 14x22 bass drum. The "R" denotes that you have a RIMS style mount on your drum. This drum case is slightly larger to accomadate for the extra hardware. For example, an 8" deep by 10" diameter rack tom with a RIMS style mount would be an 8x10R. Please ask us if you have any questions. Beato Pro 1 Djembe Bag - 14" (with Pro Drum Logo)
