I have a sil tarp by Unsponsored, 2.2 x 1.5m @175g with 1.5mm GITD dyneema cordage, packs to the size of a grapefruit
I've also got some cuben fibre bits but let's not go there
that sounds perfect
Nice Library of Congress link.
Corso,
The tarp only has 8 tie out points, this impacts slightly on it's versatility. But it is 250g.
The poncho is 680g, which is very heavy, even for a tarp.
Have you looked at the Alpkit Riga 3.5 (270g)? or the RAB SilTarp 1 (200g)?
Just some thoughts for you
Julia
The RAB SilTarp 1 looks just the ticket
