Okay. Of the more than 15 North American kilt making companies, more are going to the Poly Viscose material (virtually ALL from the same manufacturer).

After a recent "spirited" conversation on the stuff, here's what the manufacturers had to say about it.

Poly Viscose:

Poly Viscose is a RAYON fabric made from a cellulose ester (obtained by treating cellulose with caustic soda).

Viscose fabrics have a silky to matte luster with an elegant flowing drape. The natural effect of the colors gives them an attractive look. Viscose is supple and has a softness that is comfortable to wear.

As they can absorb perspiration quite quickly, making them very skin-friendly, but with poor thermal properties.

Cellulose, usually derived from tree trunks, is converted into a highly viscous state and spun into a fiber by forcing it through spinneret holes.

It is not to be confused in ANY WAY with a 13 or 16 ounce wool. It is MUCH lighter than the traditional materials used for kilts. It IS, however, light weight and easy to care for.
