Gravity works the same on wool underaprons as leather sporrans. Wasn't that colonel in the notorious underkilt shot with the Queen Mother wearing a sporran? Seems the sporran can lay on the wool and prevent its natural collapse between the legs.

Vests and jackets have pockets.

Would like to see a leather sporran rig designed to be worn like a shoulder holster - up out of the way.

When you're walking a lot,or hiking, why would you want your sporran beating up your boy parts? Sure, you can move it to one side...but that sorta makes a loud statement.

Better to leave it home and wear a jacket or vest instead.
