Sumobaby Portable Blackout Window Curtains & Blinds 75"x60" — Self-Adhesive, No-Drill, Cut-to-Fit

Sumobaby 75" x 60" portable blackout curtains are self-adhesive, cut-to-fit window blinds that block virtually all incoming light and provide instant privacy without drilling.

These blackout window blinds combine a reflective silver backing with a dense black polyester face to deliver near-total darkness, improved temperature control, and a clean, matte finish. Designed for easy installation, they attach with supplied hook-and-loop tape so you can mount them on glass, painted walls, metal frames, or other flat surfaces and remove them later without damage. The fabric is lightweight yet sturdy, stain-resistant, and can be trimmed to size for irregular windows, vehicle windows, dorm rooms, or rental spaces.

How effective are these blinds at blocking light and UV?

The fabric uses a dual-layer construction — a matte black outer surface and a reflective silver inner side — to stop light and reduce ultraviolet exposure. In most installations, the panels achieve near 100% blackout when fitted to cover the window area fully.

• Upgraded reflective silver backing for heat and UV rejection
• High-density black polyester face to absorb and block light
• Recommended to cut slightly larger than window for best seal
• Seams and edges help minimize light gaps when installed

How do I install these without drilling or tools?

Each blind ships with 25 pairs of self-adhesive hook-and-loop tape designed for strong adhesion to flat, clean surfaces. Simply position the panel, press the loop side to the mounting surface, and secure the hook strips on the blind — no screws, no brackets.

• Peel-and-stick hook-and-loop tape for tool-free mounting
• Works on glass, painted drywall, metal, and aluminum frames
• Press firmly for a secure hold; remove slowly to avoid residue
• Extra tape pairs included for larger or multi-panel installs

Can I trim the curtains to fit odd-shaped or smaller windows?

Yes. The special fabric is easy to cut with household scissors, letting you create custom shapes and sizes. For optimal light blocking, cut panels slightly larger than the opening and trim gradually until you achieve the desired fit.

• Cut with scissors to adapt to window size and shape
• Trim slightly oversized for better edge coverage
• Clean cut edges resist fraying thanks to the fabric weave
• Good for DIY applications in homes, vehicles, and rentals

What is the material like and how do I care for it?

The blinds are made from thick, high-density polyester that balances durability with a soft hand-feel. The black matte front offers a sleek appearance while the silver back adds reflective performance; the surface is stain-resistant and easy to wipe clean.

• Durable, lightweight polyester with a soft texture
• Matte black exterior for minimal glare and a modern look
• Silver-gray backing reflects heat and light away from windows
• Wipe with a damp cloth; avoid machine washing for longevity

Who this is for: These portable blackout blinds are ideal for renters, shift-workers, parents of light-sensitive sleepers, frequent travelers, and students who need quick, non-permanent room darkening. If you want a no-drill solution that can be cut to size and used across bedrooms, nurseries, dorms, campers, or cars, Sumobaby's 75" x 60" panels offer a flexible, reusable option that prioritizes privacy and light control.
