In reply to andyd1970:
I have a regular sized xtherm, if I recall its almost exactly as long as I am tall. Its the best mat I've come across, a massive upgrade from a prolite 4.
Naturally it has its limitations, the materials are quite light and thin. The regular size is narrow, too. Apparently some people don't like the noise, I don't notice/mind it.
(Xthem isn't self inflating, I prefer that style now. My prolite was harder than pack, especially with a hand injury, more bulky once packed and after a while hardly self inflated anyway.)
