I've worn my SportKilts for a long time and was (and am) completely comfortable in them.
HOWEVER... Now that I have my traditional Stillwater Kilt, I have become a "at the belly button" wearer / convert.
I don't know why, but it just feels more "secure" to me. I'll still wear my SportKilts, of course. But I think my Stillwater kilt (or kiltS, as I'm about to order another one) will get the nod most of the time from now on. I guess I like the traditional "look" as well. 8)
