Two Plies 7-mil Film (14-mil Total) Balanced Depth Moderate Sustain Cutting Attack Plenty of Durability Evans G2 Clear Bass Drum Heads feature greater durability and projection power than G1 Clear Heads, thanks to their two-ply design. Each ply is 7 mils thick - so 14 mils total - that grant you very balanced depth, sustain, and attack. Clear G2 heads are known for tons of resonance with only a bit of attack up front, making them excellent for quieter genres of music and the recording studio. The clear, smooth surface on this head boosts attack power. Brand Evans SKU 100414181_NP-1020700290 Model BD22G2
