I make kilt liners - a strip of fairly sturdy woven cotton material with - depending on how I feel and the length of time to work on it, - either a few small pleats or proper darts to narrow it to the waist.

I make it long enough to go right along the waistband of the kilt and either pin it to the kilt waistband on the inside, so it literally lines the kilt, or fold it over like a kilt and close it by the most convenient means.

However - except for my very lightest kilt I have never noticed that there was any benefit in extra insulation with or without a liner.

For protection from the cold, something over the top of the kilt and longer than it is, to hold the warm air, is by far the most effective option I have found so far.
