100% Polyester Sleep-ready darkness, fast – You’ll dim harsh daylight so naps and night-shift sleep come easier; choose darker colors for maximum block. (Results vary by color, room & light.) Thermal comfort & energy savings – The insulated weave helps reduce heat/cold transfer so rooms feel steadier across seasons. Quieter, more private spaces – The dense fabric helps dampen everyday noise and shields your room from outside view. Easy fit, flexible look – Use back tabs for a tailored pleat or the rod pocket for a relaxed fall; works with most standard curtain rods. Care is simple – You can machine-wash and tumble-dry low; no special tools needed to refresh your space.
