Zzzleepwear for Men: mey Expands CELLIANT Viscose Collection

Following on the success of the Zzzleepwear collection for women, which launched last holiday season, German bodywear company and CELLIANT brand partner mey is expanding the collection with a new line for men. This is the first menswear collection to be infused with nature-based CELLIANT® Viscose.

This capsule collection will feature four products at launch in the relaxing Indigo colorway, available in size S-XXL, consisting of short pants, long pants, a short-sleeve shirt and a long sleeve shirt. Fans of our prior Lahgo sleepwear collaboration will no doubt enjoy the new men’s Zzzleepwear series.


We’ve all heard the term work-life balance, but the Zzzleepwear collection asks us to consider sleep-life balance, because good sleep is absolutely critical to living our best lives. CELLIANT helps promote a more restful sleep by capturing and converting body heat into infrared energy, which is reflected into the body, causing increased local circulation and improved cellular oxygenation. These increases and improvements:
CELLIANT’s sleep and wellness benefits are in addition to the environmental benefits of CELLIANT Viscose, our innovative product that is made from wood certified by FSC® or PEFC™, which guarantees the origin of the raw materials is in sustainably managed sources.

CELLIANT Viscose is made in partnership with Kelheim Fibres, the world-leading manufacturer of specialty viscose. Kelheim Fibres was awarded a dark green / green shirt in Canopy’s 2021 Hot Button Report, which not only stands for responsible raw material sourcing but also is an overall sustainability indicator for viscose fibre producers.

As our CEO, Seth Casden, put it: “The development of the first-ever men’s collection CELLIANT Viscose nightwear shows further evidence of the success of the partnership between us, Kelheim and mey, bringing together fiber innovation into another commercially available fabric and product from mey, the esteemed bodywear manufacturer.”

Products by mey are available both online as well as at retail stores worldwide. For more information, visit mey.com.
