The Virtue PF pods, are without a doubt one of the top pods on the market. Their revolutionary lid design makes it easier for players to reload on the fly. The PF stands for "Press Flick" which refers to how you open the lid, instead of using your thumb to ajar the lid which can sometimes be difficult, the PF pods feature a button that you simply put pressure on, and then flick the lid open, it is that easy. The PF pods come in two different sizes, the PF 135 and the PF 165, the number refers to the number of paintballs they hold respectively. The PF 135's are designed to reduce the size of your pack, and while they hold a few less paintballs than a standard pod, they are about two inches shorter. The PF 165's are designed for players who like to shoot a lot of paint, as they hold about twenty five more paintballs than standard pods, but are the same dimensions as standard pods. Mix and match, or get all of one kind and see the instant advantage these pods give you!
