In situations such as you describe, as well as when traveling, this is my go-to sporran. I made it from a "guide bag" I picked up at an outdoor outfitters. It has loads of internal pockets and slots for folding knife, cell phone, wallet, passport, change, flashlight, and all the usual items I don't like to be without.



Since this photo was made I've added a pewter Celtic knot button to the flap.
