Introducing the speed bag built for speed, durability and predictability: the Meister SpeedKills. Constructed from 100% genuine cowhide leather, this speed bag is built to take a beating and keep coming back. The inner latex bladder provides for lighter and faster performance than traditional rubber bladders (Note: latex bladders need to be reinflated regularly). Each Meister Meister SpeedKills is produced and balanced by hand to ensure a symmetrical shape and predictable rebounds. Seams are reinforced for added durability. SpeedKills are available in 3 sizes for different skill levels: Small (7.5 x 5) for experts. Medium (9.5 x 6) for intermediates. Large (10.5 x 7) for beginners. With a premium design and feel, this speed bag is the perfect addition to any gym or home. Step up to the best and start killing it!
