I ordered a Pittsburgh Kilt with all of the pockets and the matching sporran. I keep my wallet in the sporran, my huge batch of keys go into the large pocket on the front of the inner apron (helps keep the apron down in the wind). The side pockets are quite invisible, and so far unused. The rear pocket is good for shopping lists and such.

Pockets are good.

I'll be getting a Bear Kilt and I've ordered a simple leather sporran to wear with it. I'll find out if the sporran is adequate, but I suspect there's a Freelander sporran in my future.
