Snare drumhead. This 14'' drumhead is featuring the latest innovation from D'Addario, a newly patented UV cured coating. It is the most consistently applied coating ever seen on a drumhead. In addition to D'Addario's new coating, the UV1 also features a new 10 mm film. This film type is known to have warmer tonal characteristics while being more resistant to stretching and denting. Combined with Level 360 Technology, the UV1 is the most versatile and durable 10 mm drumhead drummers have ever laid their hands on.
