Without, and I agree with Mac and Schultz (hope thats not TMI!). When I wear pants I take my wallet, keys, change, cell phone off when I walk in the door and put them on the counter. No different with the sporran, although if I am going back out I can just take off the sporran and strap and have everything all together!

However, as mentioned on another thread, that is the advantage of a contemporary kilt, POCKETS! I find that I like the look of a sporran with a tartan kilt, but for every day wear, a UK or other pocketed kilt, is the way to go.
