Head-to-head
Two routes to the same darkness: block the window, or cover the eyes. Each fails in a way the other does not.
The short answer
Curtains if the room is the problem for more than one person and you can hang them properly — wide, high, with a wraparound rod. A mask if you travel, rent, share a room with someone who wants light, or want darkness to be complete without carpentry. The curtain's fabric is opaque but its edges leak; the mask's seal is complete but it is on your face. The most reliably dark bedrooms use both.
NICETOWN
Best for: Bright bedrooms, streetlights, shift work, and couples where one person refuses a mask.
Trade-off: Edge leakage is a hanging problem the curtain cannot solve for you.
Manta Sleep
Best for: Side sleepers and shift workers who need daytime-grade darkness and have been let down by flat masks.
Trade-off: Bulk and price: it is the largest and dearest mask in our catalogue.

When each one wins
The SleepOriginal verdict
Curtains solve the room; a mask solves the person. Couples and homeowners should hang curtains and hang them well; travellers and renters should buy the mask; and anyone who has both a bright window and a light-sleeping partner should do both.
Questions
The fabric of a true blackout curtain does; the gaps around it do not. Mount wide and high, use a wraparound rod and overlap the panels, or expect a glow at the edges.
