Harnesses and vests are a essential gear to carry paintballs during playtime.
A majority of paintballers will use a harness/pod pack to hold pods which contain paintballs in them. This allows the user to fill paint right on the fly during play without having to leave the game/field to reload.
Vests are also another option to carry paint as well. They provide upper torso protection and some can even hold a tank! Vests are ideal for those looking to play a milsim/scenerio paintball style. Vests also allow players to add patches, other types of customizations.
