This new tank from Innokin is stylish and durable, and completely compliant with the new TPD regulations. The new push and twist top cap is both easy to remove and safer with children about. The tank is stainless steel construction and uses less glass to make the tank more durable and less likely to break if dropped or carried in a bag. The Slipstream is a powerful mid-range tank with 3 adjustable airflow holes. Use a tighter draw to simulate a cigarette style draw and intensify flavour or open the holes to produce bigger vapour. The airflow is from the top of the tank to eliminate those messy leaks you get from bottom airflow holes.
