I agree - take the leather tassels off the Stillwater nightstalker sporran made from ballistic nylon. Or, Amerikilts makes a cloth sporran, not sure how it'd hook up to other kilts.

Many small camera bags, carry pouches can be adapted for use as a sporran. Or just drop wearing a sporran and put your stuff in a vest or jacket.

Or buy one of the many kilts with built in pockets.

Lots of options for you.
