I wear a small black belt pouch designed to fit over wide belts like kilt belts, when I go golfing without a sporran or am kilted without a jacket or vest for extra pockets, as I carry a lot of stuff that will not all fit in a sporran. It is small enough to not be intrusive, but big enough for car keys, cell phone small wallet, or for three golf balls and tees, etc when golfing. Seen here:





Worn over my left hip, but could be owrn either side or off midline front, with tubing tucked into the waistband of the kilt and then up under your shirt to your skin site. Available at a variety of kilt shops but you can find others online or on ebay. Just make sure it is big enough to go over your wide kilt belt.
