Original Integral Designs 8' x 5' (1520x2440) Siltarp. Colour Olive. Weighs 208g, rolled, in the original, sensible sized storage sack.
Made in Canada by ID prior to the takeover of ID by RAB.
Found this one in one of my gear tubs and I'm pretty sure that it has never been used. So essentially, it's new.
Cheapest I can find the current chinese made RAB model on the net is A$113 plus post.
