Linen Matte (243 GSM, 100% Polyester Filament) is a light-filtering curtain — heavier, with a smooth matte surface that significantly reduces glare and provides better daytime privacy. Dune Classic (148 GSM, cotton-viscose-polyester blend) is a true sheer — lighter, more translucent, with a natural fiber character that Matte lacks. Both have a warm, sandy tone, but they behave very differently. If you want to maintain the openness and brightness of a sheer, Dune Classic is the better choice. If you need to cut glare and increase privacy, Linen Matte does more work.
