The Aquarian VEL13 Hi-Velocity 2-Ply 13″ Satin Texture Coated Batter Snare Drum Head features a reverse Power-Thin Dot in the center for added reinforcement. The Safe-T-Loc Hoop prevents slippage inside the hoop so that the head does not de-tune during a performance and will not pull out. An exclusive Sound Curve Collar Design allows the drumhead to seat perfectly on the bearing edge. This head conforms instantly to any shell design. Extra-Warm Drumhead Film produces a rich, warm and full mid range sound on toms and more low end on bass drums. It eliminates the ping and plastic sound common to other drumheads. The Texture Coating is extremely thin, and it provides a more responsive surface for brushes and sticks. It does not chip off and it outlasts all others.
