The Innokin Zenith 2 Tank is the latest tank from the award-winning platform series. It has a precise airflow for tighter and smoother mouth-to-lung (MTL) vaping and a larger airflow gate for restricting direct-lung vaping. The top cap of the tank has a silicone seal port which prevents messy leaking when refilling. The Zenith 2 tank boasts a super-easy twist to fill top cap and an easy to clean replacement system. It is compatible with the entire line of Z-Coils.
