The Remo M6-0715-F1 7" Bongo Head features the same hoop as heads used for drum kits; the skin is tougher, more durable, and available in different film thicknesses. The lighter weight models resemble goat skin heads, whereas the slightly denser heads mirror the head weight of mule or cowhide heads. The M6-0715-F1 Fiberskyn 7" Remo Bongo heads are weather and climate resilient, making them easy to tune and play in all.
