These bumpers are made of the same material as the Dokken Dead Fowl Trainers (DFT's) (Canada Goose, Mallards, Teals, etc). The Dokken Foam Super Dummy has that natural feel foam. The 2" Foam Super Dummy WILL NOT SINK! These trainers will float, even when punctured. Training scents may be injected directly into these bumpers for added realism.
