Dunlop 9023R Thumbpicks SHELL Plastic Large

In general a male needs the large size thumbpick; this was for me a good fit. For the medium size ones you need really slender fingers. This thumbpick gives a really nice clean sound on the bass strings.

Fits on my medium thumb! Nice loud volume. I used it to play banjo and prefer the sound of a metal pick, but I think the plastic one could be great on acoustic guitar.
