I need a fresh product concept for an adult-sized sleep mask made from cotton. The design must sit comfortably on an average adult head, contour well around the nose and cheeks, and stay breathable through the night without causing pressure lines. Because I skipped the “primary function” question, you’re free to get creative: light-blocking is essential, but if you can incorporate gentle noise-reduction panels or a pocket for a thin sound-therapy speaker insert, I’m open to exploring that too. Just make sure any added elements remain lightweight and machine-washable so we preserve cotton’s natural softness and hypoallergenic appeal. Here’s what I’d like delivered: • A detailed CAD or vector drawing that shows front, back, and cross-section views. • A tech pack specifying fabric weight, stitching patterns, elastic type, and trim dimensions. • A short material sourcing note listing at least two suppliers that can provide the recommended cotton knit or woven cloth at scale. • Optional: a prototype pattern (PDF) ready for laser cutting or manual cutting, graded for standard adult sizes. I’ll review for fit ergonomics, completeness of the tech pack, and practicality of mass production. Once the design checks out, I plan to move straight into prototyping, so accuracy now will save us both time later.
