Zzzleepwear series


The world’s first nightwear that converts body heat to energy with CELLIANT® viscose.

Good news for anyone who has endured restless nights: just slip on our nightwear and enjoy healthy sleep.

25% of people worldwide are currently affected by mild to severe sleep problems. Stressful days are often followed by stressful nights – with far too little restful sleep. In the Zzzleepwear series with N8TEX®2.0 technology, CELLIANT® makes all the difference.

CELLIANT® converts the heat emitted by the body into full-spectrum infrared energy and reflects it back to the skin. This supports local circulation and the oxygen supply to the cells.

Advantages of the Zzzleepwear series with CELLIANT®

Recharge your energy while others are counting sheep: with our innovative Zzzleepwear nightwear.

Everyone talks of work-life balance. But they often forget about the night. Restorative sleep works wonders. The Zzzleepwear series by mey sets new standards on this front: it is designed to help you fall asleep quicker and can also improve the quality of your sleep.

Its unique secret lies in the breathable fabric of the mey nightwear, featuring innovative N8TEX®2.0 with Celliant® technology, which is directly incorporated in the viscose fibres. This converts body heat into full-spectrum infrared energy and reflects it back to you as you sleep.

CELLIANT®’s commitment to quality and consistency is confirmed by stringent tests, which may include ash, emissivity, hyperspectral imaging and TcPO2 tests. For an energy boost after a restful night’s sleep.

Improved oxygen supply for better rest and enhanced performance

CELLIANT®’s scientific advisory board, which consists of experts in photobiology, nanotechnology, sleep medicine, diabetes and wound care, has overseen nine published, peer-reviewed pre-clinical, clinical and technical studies and physical tests, substantiating the effectiveness of CELLIANT® and the benefits of the infrared technology.

Tests conducted specially for mey on a small group of participants at CELLIANT® show that oxygen levels in the tissues increase by approx. 7.6% when wearing our Zzzleepwear with N8TEX®2.0 technology. This increased the oxygen supply to the cells. For a relaxing night's sleep and improved recovery.

CELLIANT® lets cells breathe: the oxygen supply to the cells increases by at least 7.6%, which is more than with any conventional fabric. In the graphic, you can see the oxygen content of the cells when using conventional fabric compared to N8TEX®2.0 technology with CELLIANT® viscose.

Benefits that pay off, day and night.
