Pearl Gray Copper-Infused Silk Eye Mask, Vesper

Hand wash in cold water with a silk-safe detergent - we recommend Soak Wash. Submerge, gently agitate, squeeze out excess water without wringing, and lay flat to dry away from direct sunlight or heat. Do not machine wash, tumble dry, or iron. The same care that protects the silk protects the copper infusion; gentle handling, cool water, and line drying will keep both in good condition wash after wash.

Silk is a protein-based fiber, unlike cotton (a cellulose- or plant-based fiber) or synthetics, which come from petroleum. Regular detergents are formulated for cotton and synthetics, which means higher pH levels and often enzymes designed to break down protein-based stains, like food, sweat, and grass stains. Both features are genuinely damaging to silk over time: high pH strips the natural proteins that give silk its sheen and softness, while enzymes degrade the fiber structure wash by wash. 

Soak Wash is plant-derived, pH-appropriate for delicate natural fibers, and gentle enough to clean without quietly destroying what you're cleaning.

Copper North's silk is infused using a bath immersion process that bonds copper ions throughout the fiber matrix rather than coating the surface. This means the copper is integrated into the fiber itself, not sitting on top of it; it doesn't wash off the way a surface treatment would. Our finished fabrics are independently tested before going to market to confirm copper is present and distributed throughout the fiber, not just at the surface.

The Umbra is contoured and sits close to the face without putting pressure on the eye area, making it suitable for wearing with lash extensions. The Vesper is generously oversized and settles across the face with more coverage - some customers with extensions find this works well, others prefer the contoured fit of the Umbra. If lash extensions are a consideration, the Umbra is the safer choice.

Yes, both models are designed with all sleep positions in mind. The silk surface reduces friction against the pillow, and neither model has structural elements that would be uncomfortable to sleep on. The Umbra's contoured form is matched to the face, which some side sleepers enjoy. The Vesper's generous coverage works well for back sleepers and side sleepers alike.

Both models are well-suited for travel. The silk is lightweight, compresses easily, and the no-pressure design of the Umbra is particularly practical for long-haul flights where comfort over several hours matters.

Yes, and the Umbra specifically is designed not to press against the eye area, which means eye cream applied before bed stays where it was applied rather than being absorbed by or displaced by the mask. The Vesper's slightly looser fit around the eye area also accommodates skincare products, while its broader coverage means more copper-infused silk surface is in contact with the skin overall.

Both models are designed to fit a range of face shapes and sizes. The Vesper is slightly oversized - it provides broad coverage and sits across rather than conforming tightly to facial contours. The Umbra is contoured to follow the face's natural shape, sitting closer without relying on size alone for coverage. If you're between the two, the Umbra suits those who prefer a precise fit; the Vesper suits those who prefer full, dramatic coverage.

Copper North's silk comes from suppliers certified to OEKO-Tex Standard 100, which tests finished textiles against strict criteria for restricted substances, pH ranges, and parameters relevant to skin contact. Silk is naturally hypoallergenic and low-friction. Copper is an essential trace mineral already present in the human body. Our finished fabrics are independently tested to confirm copper levels are within ranges established as safe for prolonged skin contact. If you have a specific metal sensitivity or dermatological condition, we recommend consulting with a healthcare provider before use.
