Black, Olive, Khaki, and Heather Grey Mocker UKs here as well as one Black Original (NeoTraditional). Have also had a Sage Survival and an Urban Camo Original. Just wash and hang them to dry. If occasional pleat curling bothers you, Steam Ironing will take care of that.

I love mine and far prefer the cut of the Mockers to a traditional kilt (or even any of the other models of UK.)
