Comfortable Sleep Mask for Restful Sleep

The unisex ergonomic sleep mask from Kalsten offers optimal light protection and high wearing comfort for home, on the go, or on a plane. With its soft, smooth surface and body-conforming shape, it provides gentle pressure on the eye areas while efficiently blocking light.

Main Features

Ergonomic Design: Contoured shape adapts to the face and nose for complete darkness and reduced pressure on the eyes.
Soft Surface: Fine, silky satin for a pleasant skin feel – ideal for sensitive eye areas.
Gentle Padding: Lightweight, form-fitting filling for comfort without bulk.
Adjustable Strap: Elastic, individually adjustable band for a secure fit on different head shapes.
Lightweight and Travel-Friendly: Compact and storable – perfect for travel, office breaks, or power naps.
Skin-Friendly and Breathable: Comfortable climate between skin and mask reduces sweating and irritation.

Benefits for the User

Improved sleep through reliable darkness: faster falling asleep and longer deep sleep phases.
Relaxed wearing comfort even with extended use thanks to soft materials and ergonomic fit.
Versatile use: ideal for nighttime rest, napping, meditation, or as support for shift work.

Care Instructions

For long lifespan, we recommend gentle hand washing and air drying. Avoid strong friction and contact with aggressive cleaning agents to protect the surface and padding.
