Bought this floorless version of the Duplex in October of 2016. I’d had a normal Duplex previously and figured this would be more to my preferences. It’s been great but I rarely use it. Made of Olive .51 oz/sqyd, the total weight (minus stakes ) in its stuff sack is super light at 305g. Search for the Duplex Tarp and you should find a few reviews like that from Ultralight Insights blog in 2016. That write up matches my experience pretty well. It’s kept me happy and dry, but I’m a tent-aholic and have had numerous shelters since then. My latest is a SlingFin Portal, so I’m posting this Duplex and a brand new MLD Duomid XL for sale. Silly to let great items like this collect dust in my garage.
