My understanding is that Viscose is the English word for Rayon. If Marton Mills were in the U.S. they would call their fabric Poly-Rayon. Rayon being synthetic cotton that so many aloha shirts are made from.

As for the kilt - If you have time to save a bit - go with the USA Kilts Semi-Trad. That way you're not wearing a cheap looking kilt to Scotland and you'll look smart while still having the Teflon protection. No need to iron if it wrinkles - just hang the kilt in the bathroom while you shower or pack a small hand steamer. Nothing simpler.

I've purchased 13 of Rocky's semi-trads and never had a problem with them. They're my go to kilts for travel - be sure to kilt up to fly over.

And, cousin, say hi to any residual kin still up around Skye Glenn near Whycocomagh.
