peekay - Yeppers, it's T-shirt material. Don't get caught up in weave, stretchiness, yada, yada, yada ... as long as it isn't shiny (and therefor slippery), it'll be fine.

My HAB is made from reject T-shirt material ... bought in a "seconds" store for $2 a metre. I've "made" them for others out of better quality stuff and they all work beautifully.

Just ask the shop keeper to show you the "cotton jersey knit" and you won't go wrong
