The cell phone holster will fit on the shoulder strap of the Bolo, Dee Dog, and El Ocho bags, but is NOT compatible with the Pee Wee or commuter bags. Owners of these bags are advised to wear the cell phone holster on their belts (yes, it has belt loops, too!), but not too close to the groin, because god knows what all those radio waves will do to your privates! Yow!
