Remo Emperor Black Suede Crimplock Marching Tenor Heads are made with two 7-mil plies of film: a top high-strength Ebony layer that has been treated with Remo's Suede process, and a clear underlying layer that gives the head better sustain and heat resistance in the hot summer sun. This head produces a focused tone and feels soft under the hands (which is great after your third rehearsal block), and they look very contemporary. The textured finish makes these heads non-reflective so you won't go blind on the field.
