Venum HURRICANE DOUBLE ENDED BAG You demand the best for your training! The Venum HURRICANE DOUBLE ENDED BAG is designed to provide high speed movement. The Venum Hurricane Punchball allows you to improve your reflexes, movement, and timing. As the name suggests, it has two attachments, one fixed into the ground and one fixed on the top. These attachments create tension on the bag and compared to a traditional speed bag, this tension offers a greater range of movement. Punchball allows you to work with dynamic movements on offence and on defence. PU is extremely durable thanks to the reinforced seams and the robust lacing.
