Evans clear G2 series, one of the most popular drum heads on the market, features two plies of 7mil film that provide a high level of consistency and durability. The perfect blend of depth, sustain and attack makes small toms sing and floor toms growl. Evans Level 360 technology is incorporated to extend the level playing surface of the drumhead, 360 degrees around the drum. The vertically enhanced collar design guarantees even contact with the critical bearing edge of the drum shell, resulting in: ease of tuning, extended pitch range and optimum quality of sound. Evans Level 360 technology resolves the age-old dilemma of traditional synthetic heads consistently not fitting the drum shell without using considerable force.
