NXE (SP4) 4 pod harness Series  are designed for durability, comfort and ease of use at a mid-level price.  The non slip back pad will prevent the pack from sliding around and bouncing on your during play.  This will help you focus on your game not on your pack.  The almost frictionless pod ejection system will make your 140rd pods slide out easy when you need to get to them quickly.  The sure grip pull tab will guarantee you release one pod at a time the first time.
