100% Waterproof Outdoor Curtains 54x84 inch, Dark Grey

Yarn dyeing is the detail that matters here. The color goes into the thread before the cloth is woven rather than onto the surface afterward, which is why these hold their Dark Grey through a season of direct sun where a surface-dyed panel goes chalky. The fabric is UV resistant as well, so the sun works on neither the color nor the weave.

The thickness does two jobs. It makes the panels completely opaque, which turns a pool deck or a gazebo into a place you can sit without being watched from the next yard, and it makes them fully waterproof while still breathing, so rain, snow, and heavy wind stay outside. Two panels come per package at 54 by 84 inches each, hung from silver rust-proof grommets with a 1.6-inch inner diameter.
