Maxpedition Fatboy S-Type Versipack
The MAXPEDITION Fatboy S-Type Versipack (#0408) was originally designed for Search and Rescue work, the S-type allows for MAXPEDITION's accessory pocket in place of the cellphone pocket on the standard Fatboy.  The Fatboy S-Type rides on the left side of the body filling the need for a 'lefty' Fatboy and a grab-and-go gear bag that does not hinder the quick drawing of a sidearm on the right hip.
