(Item: 757242150221) Remo PS0310MP 10" Crimplock Drumhead Clear Pinstripe: The Crimplock hoop is a hybrid design combining a crimped leg over the Weatherking poured channel technology, locking the film into the collar for added strength and durability in high-tension marching applications. Featuring two 7mm plies of Mylar combined with a patented dampening process, the Clear Pinstripe is legendary for its attack, projection and tone.
