Have a very lightly used ultra light ultra SIl tarp by Sea to Summit in medium. Extremely lightweight, durable and fully waterproof. I have the Large version I use mostly. Absolutely no tears/rips, and the seam seal is intact. I stored this in an airtight tote, never in the stuff sac (which is included). Has 6 tie outs with locking tensioners. Just over 10oz for a 6’6″x8’6″.
