SLACKiES are a little thicker than most standard polyester strings which provides strong binds and excellent slack potential. They hold tension really well and have a slightly heavier weight which makes them perfect for long practice sessions and complex whip tricks. The majority of the iYoYo Pro Team has already switched over to SLACKiES and hasn't looked back! Pick up a pack and throw some slack!
