These inverted napa heads are great! The top layer that you hit is plastic and the napa layer is on the inside. They have a nice aggressive attack but without the tinnyness of many plastic heads. The napa keeps the sound nice and warm.
Plastic top layer with napa on the inside is reverse from the usual napa heads which are prone to breaking over time. Especially if the player does not hit the drum correctly!!!
Unlike goat skin these heads are waterproof, great for the Pacific Northwest!
