Nature-based CELLIANT® Viscose powers the Zzzleepwear Series from mey

CELLIANT Viscose makes its global debut in nightwear in mey’s newest collection, the Zzzleepwear Series. mey, creators of premium underwear, nightwear and lingerie, have had sustainability as one of their foundational pillars since their inception in 1928, and so CELLIANT Viscose is a perfect fit for their new line.

After all, nature-based CELLIANT Viscose is FSC® or PEFC™ certified, which guarantees the origin in sustainably managed farms. It is also REACH certified, OECD certified for biodegradability, and is registered on the USDA Biobased list. In addition, our partners in creating CELLlANT Viscose, Kelheim Fibres, are world–leaders in sustainable viscose solutions and raw materials sourcing, having been recognized with a dark green shirt in Canopy’s 2021 Hot Button Ranking.

Beyond sustainability, CELLIANT Viscose brings unique performance qualities to the sleepwear collection. All ten launch pieces from the Zzzleepwear Series are powered by CELLIANT Viscose, which captures and converts body heat into infrared energy. This increases local circulation, helping keep you at the perfect temperature, sleep better and recover faster from physical activity. All so you feel refreshed and ready to take on the day when you wake.

Matthias Mey, Managing Partner of mey, puts it like this: “Sleep is the most rejuvenating time of the day and with the added therapeutic infrared properties of CELLIANT technology combined with the soft, lightweight viscose fiber, our product should make it even more restful and restorative.”

Our own Seth Casden, Hologenix co-founder and CEO, asked to reflect on an incredible partnership between three brands, noted, “The development of this first-ever CELLIANT viscose nightwear available worldwide is a testament to a true partnership between us, Kelheim and mey, bringing together fiber innovation from two companies into a commercially available product from mey, the esteemed bodywear manufacturer. We hope to positively impact the lives of the people that are using our products.”
