The Pogo is one of the four footbags we have here at Dragonfly that have an all metal filler. As stated in the description for the Nathan Deschamps Metal 32, this footbag is one of the best footbags you can buy right now. The all metal filler increases the weight of the footbag giving you the edge on stalling, but also doesn't compromise pop. Get yours today because these are going fast!
