I posted that review. The Hennessy page says their Hex Tarp weighs 23 oz. I don't have a scale but this tarp weighs considerably more than my 30 oz. hammock. It also packs to 5 x 11" not 3.5 x 11" that Hennessy states. Mine is a knockoff. If I return it I lose $8.00 but Amazon said they would give me an additional $30 goodwill credit.
