Evans ST (Super Tough) Dry snare heads deliver a desirable level of volume and ring yet responds to the slightest contact. The ST Dry coated drumhead features two plies of 7.5mil film for extra durability and full bandwidth rimshots—while this dry version also reduces overtones and controls sustain, thanks to the precision-drilled vents around the perimeter. Evans ST Dry snare drumheads have a more defined attack, with less than average sustain, and moderately bright tone, plus the added durability of Evans premium coating. This coated head also features Level 360 Technology.
