Comfortable 3D Sleep Mask for Restful Sleep

The Kalsten sleep mask is an anatomically shaped 3D eye mask that intentionally creates space above the eyes. The shaped eye sockets provide enough room for the eyelids – ideal for natural blinking, eyeshadow, or mascara. Perfect for travel, shift work, power naps, or undisturbed nighttime rest.

Product Features

Shape: Anatomical 3D shape with pronounced eye sockets for pressure relief
Core: Lightweight, pressure-relieving foam core for comfortable padding
Outer Material: Finely structured, breathable cover for a pleasant skin feel
Band: Elastic comfort band with flexible hold without pulling
Nose Seal: Customized contour at the nose bridge reduces light gaps
Weight: Very light – ideal for on the go or to take along

Benefits

Maximal Darkness: the tightly closing shape effectively blocks distracting light
Gentle Fit: shaped cavities prevent pressure on eyes and eyelashes
Universal Fit: elastic band adjusts to head size, suitable for travel and everyday use
Versatile Use: sleeping on planes, trains, in the office, or at home

Care Instructions

Hand wash recommended: wash cold with mild detergent
Do not bleach, do not tumble dry; let air dry
Gently brush or wipe if necessary to maintain shape and structure
