The Esteh portable blackout curtain is constructed from 420D Oxford polyester with a silver polyurethane coating on the reverse side. This dual-layer design is engineered to reflect heat and provide a 98.4% light occlusion rate. The system uses 40mm PVC suction cups rated for a static load of 1.5kg each, providing enough strength to hold the curtain securely against the glass.
The "Velcro-edge" design allows users to down-size the 36 x 57-inch panel to fit specific window frames precisely, which helps prevent light leaks around the edges. While the fabric is highly durable, tight folding for travel can create micro-creases in the silver coating over time, so rolling the material for storage is a helpful practice to maintain its appearance and performance.
Summary: A well-balanced middle-market option that offers adjustable sizing and effective light blockage for transient living or travel.
For a similar suction-cup style in a larger size for wider windows, the Amazon Basics 50 x 78-inch shade provides broader coverage.
