NICETOWN has been making window treatments for years, and their 100% Blackout Curtains solve one specific problem well: blocking light completely. The Navy set we tested uses a sewn-in black liner backing that stops 100% of sunlight and UV rays. That means no morning glare, no streetlamp bleed-through, and no washed-out colors on your furniture.

Each pack gives you two panels, each 52 inches wide by 95 inches long, for a total width of 104 inches. The polyester blend fabric feels dense and substantial, not flimsy. The 2.7-inch rod pocket works best with a rod no thicker than 1.7 inches, which lets the curtain slide freely. You can pinch the fabric to create pleats for a more tailored look, though they hang cleanly out of the box. In real use, the room stays pitch black even on a sunny afternoon. That makes a noticeable difference for shift workers or anyone who needs total darkness for sleep.

One limitation: the polyester material isn’t breathable, so the room can feel stuffier than with lighter curtains. The Navy color is rich and doesn’t fade after several washes, but the fabric does wrinkle if you fold it tightly. For the price, these deliver reliable blackout performance without fuss.
