thermal fabric weave help

AND knits! BTDT. I was LOOKING for the wicking tec fabrics and got them AND the lovely old woven stuff.

Old fashioned woven cotton pique is brilliant for some uses, but I wanted a wicking, quick-drying tough stretchy modern type thing to make a rash vest for James. In the end I couldn't get what I needed in time, and he didn't really want one... Now, having suffered at Soustans back in the summer with twigs and other stuff working down inside an ordinary T shirt, he has seen the light! I'll do one for next time he goes off wind-surfing, kayacking, and white water rafting. No point right now, as he'll have grown out of it by the next opportunity to do it.

Looks like what I know as "airknit", which is typically done in a wicking poly.
