Barami is very insecure for outdoor carry. Much better suited for IWB strong side carry. But I promise you that with acrobatics it is apt to pop loose. Acrobatics like tripping over a log, etc.

I like nylon or Kydex for exposed outdoor holsters. I've had no problems ever with Uncle Mike's products (though they aren't glamorous). As for Kydex, well.. I make Kydex holsters and I often carry a pistol in a Kydex holster with a Kydex "flap" (actually a swing-back cover) in the woods. HOWEVER, it IS noisy!
