Certifications and highest quality.

The Superfine Organic series for women and RE:THINK series for men are GOTS certified. The standard assesses social criteria and environmental requirements for textiles made from organically produced natural fibres. As of 2021, all three of our company locations (Germany, Portugal and Hungary) are GOTS-certified. We have also been able to convince one of our CMT partners to undergo GOTS certification.

The standard guarantees the sustainable production of textiles. It begins with organically and sustainably cultivated raw materials, continues with an environmentally and socially responsible manufacturing process and even includes the designation of products. GOTS is the leading global standard for textile products consisting of at least 70% organically produced natural fibres.

The Grüne Knopf is a government-run certification label for sustainable textiles from the German Federal Ministry for Economic Cooperation and Development.

Both the products and companies are tested. The Grüner Knopf lays down mandatory standards to protect people and the environment. A total of 46 stringent social and environmental criteria must be met that cover a wide spectrum from wastewater to forced labour.

In product testing, manufacturers must verify that environmental and social criteria are met based on existing labels (such as GOTS).

Mey is the first company in Germany to bring FSC®-certified textile garments to the market. This makes the company one of the first in the world that is allowed to feature this certificate for FSC®-certified clothing.

The Forest Stewardship Council® (FSC®) is an international organisation that promotes the environmentally responsible, socially beneficial and economically viable management of the world‘s forests. FSC® chain of custody certification ensures that products with the FSC® label make a genuine contribution to sustainable forest management.

With these certifications, we ensure that both the raw materials for the lyocell and modal fibres of the TENCEL™ brand and the viscose fibres of the LENZING™ ECOVERO™ brand, which are made from wood, are sourced from sustainably certified forestry. We can also guarantee that our packaging is sourced from environmentally friendly and ecologically sustainable forestry.

To receive the STANDARD 100 by OEKO-TEX® label, every part of a product (lace, fabric, thread, hooks, eyelets, tape, etc.) must meet the criteria. That means our products are free from banned and regulated contaminants as well as hazardous chemicals. Moreover, the pH value is tested for its skin-friendliness and the colour authenticity of each item is verified.

As a result, our customers can count on purchasing an impeccable product.

MADE IN GREEN by OEKO-TEX® is a exacting and traceable product label that ensures the environmentally and socially responsible production of textile products. It also guarantees that the items are free from harmful substances. In order to unite these aspects in one product label, the MADE IN GREEN by OEKO-TEX® label is based on STANDARD 100 by OEKO-TEX® product certification, which requires the items to be tested for harmful substances, and on STeP by OEKO-TEX® production facility certification, which ensures sustainable processes and socially responsible working conditions in production.

A clear product ID and QR code on the label gives customers the opportunity to trace each item and its main components back to specific countries and production facilities. As our supply chains become increasingly complex, there is an increasing demand from our stakeholders for documentation and transparency.

mey joined the Partnership for Sustainable Textiles in 2020. The partnership was established in 2014 by the German Development Minister Dr. Gerd Müller in response to increasing numbers of accidents in textile factories in Pakistan and Bangladesh.

The goal of the multi-way partnership, consisting of businesses, NGOs, unions and the German federal government, is to improve working conditions in textile production worldwide. Practically, these goals are promoted through cooperation and joint projects in the local area.

The new /myluxuries segment by mey guarantees the highest-quality materials and careful processing in the manufacturing of the products. The series with the gold label meet our highest standards. The fabric and comfort merge into one perfect mey product.

We currently have two series in this outstanding mey quality: the Superior series and the Business Class series.

Lyocell and modal fibres of the TENCEL™ brand feel exceptionally soft and gentle against the skin. These are synthetic fibres that are produced in an eco-friendly process and made from wood cellulose sourced from sustainable forests. 

TENCEL™ modal and lyocell fibres ensure excellent moisture wicking and keep the body cool and dry. The fibres are also extremely skin-friendly, durable and visually appealing, thanks to their subtle sheen.

TENCEL™ is a brand of Lenzing AG.

The LENZING™ ECOVERO™ fibres are produced in an environmentally friendly manufacturing process to high environmental standards. The wood used comes from renewable sources with FSC® and PEFC™ certification. These confirm that the wood is sustainably sourced.

LENZING™ ECOVERO™ are extremely efficient to produce, generating 50% fewer emissions and consuming 50% less water than generic viscose. In addition, the manufacturing process is certified with the EU Ecolabel: this confirms its considerably reduced environmental footprint.

TENCEL™ is a brand of Lenzing AG.

In our best-selling Emotion series for women, we also use high-quality viscose fibres from ENKA®. The synthetic viscose fibres are made in Germany and are made from up to 100% FSC®-certified wood cellulose sourced from pine and spruce from sustainable forestry in Scandinavia or the USA. The trees are grown without artificial irrigation, fertilisers or pesticides. 

Products with viscose fibres are exceptionally smooth and relatively crease-free – so there’s no need to iron them after washing. They also feel comfortable against the skin and effectively absorb moisture.

We use innovative COOLMAX® fibres for mey underwear with a climate-regulating effect. The special feature of these quick-drying polyester fibres is their propeller-like fibre structure, increasing their overall surface area by up to 25%. 

These combined properties of the fibres and their capillary effect allow moisture to be absorbed from the skin more quickly and efficiently and wicked to the outside of the fabric. As a result, the Dry Cotton and Dry Cotton Functional series, the Zzzleepwear series and the Mood series for women offer excellent moisture regulation and high breathability.

Lycra® fibres were invented over 60 years ago and are valued for their lightness and invisibility in the fabric. Lycra® fibres provide an optimal fit compared with pure cotton, thanks to their stretch properties – even when the body is in motion. The products are extremely durable and simply unobtrusive to wear.

At mey, Lycra® is used in various basic series and seasonal series.

CELLIANT® technology incorporates a mixed mineral powder in the viscose fibres. This converts body heat into full-spectrum infrared energy and reflects it back to you as you sleep, recycling the body’s own energy.

CELLIANT®’s scientific advisory board, which consists of experts in photobiology, nanotechnology, sleep medicine, diabetes and wound care, has overseen nine pre-clinical, clinical, technical and physical tests, as well as eight published, peer-reviewed studies by experts, 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.

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.
