The latest in gravity defying freestyle footbags is the diminutive Dirtbag Mighty Mite, which comes filled with steel B B’s. The Dirtbag Mighty Mite is quite small, with an approximate diameter of 1.75 inches across.
Filled with stainless steel miniature ball bearings this synthetic suede 14-panel bag weighs about 60 grams. The Mighty Mite is made specifically for “high dexterity” (fast and difficult) freestyle moves. See a picture of the Mighty Mite along side a regular sized Dirtbag below, for size comparison.
