the UK has a narrow apron in front.. the AK has a standard apron... to me I like the narrow apron, it falls into place instantly.. I also like the cargo pockets on the sides. there are others that don't like the narrow apron or pockets, it comes down to what you want in a kilt. I have 2 UK's and think the quality is very good. I have had my first UK for 3+ years and wear a kilt pretty much daily.. it still looks great.
