The Story

Why we created
Silk With a Purpose™.

Not everyone wants a new pillow. But many people wanted our silk pillowcase.

For years, our biofunctional silk was available exclusively on the enVy® Pillow, combining premium Mulberry silk with Canadian enVy COPPER® Technology. Supported by independent laboratory testing, we believed silk could be more than a luxury fabric—it could become a biofunctional sleep textile.

Over time, we heard from customers who loved the pillow they already slept on but wanted access to our COPPER-infused silk.

“I love my current pillow. I just want your silk.”

That simple request inspired Silk With a Purpose™.

We created our first standard Queen-size silk pillowcases, allowing people to experience our biofunctional sleep fabrics on the pillow they already know and love.

Crafted from premium 22 momme Mulberry silk and infused in Canada with proprietary enVy COPPER® Technology, Silk With a Purpose™ was designed to deliver more than the traditional benefits of silk alone.

Because silk should do more than feel luxurious. It should have a purpose.

“Traditional silk was a beautiful beginning. We believe biofunctional silk is the next step.”

Technology & Testing

The science behind
Silk With a Purpose™.

Rather than relying on silk alone, enVy® Biofunctional Silk Pillowcases are infused in Canada with enVy COPPER® Technology — supported by independent laboratory testing and designed to help maintain a cleaner sleep surface.

Canadian COPPER® Technology

Biofunctional silk designed for more than smoothness.

Most silk pillowcases focus solely on friction reduction. enVy® Silk With a Purpose™ combines premium Mulberry silk with proprietary Canadian enVy COPPER® Technology, permanently infused into the fabric to support a cleaner sleep environment while preserving the luxurious feel of silk.

For the COPPER + HYLA⁺ version, Hyaluronic Acid is added to support overnight skin hydration. The COPPER technology remains permanent; the Hyaluronic Acid component is designed to gradually diminish with washing over time.

Contrairement à de nombreux oreillers axés sur la beauté, enVy a été développé par des infirmières autorisées pour favoriser simultanément l'alignement de la colonne vertébrale et la santé de la peau. Certains modèles intègrent également la technologie enVy COPPER® infusée en permanence ainsi que des tissus en soie de mûrier ou en TENCEL™ de qualité supérieure.

Quels matériaux sont utilisés dans l'oreiller enVy ?

L'oreiller enVy est doté d'un noyau en latex 100 % naturel certifié eco-INSTITUT®, associé à des options de taies d'oreiller haut de gamme, notamment en soie de mûrier 22 momme et en tissu TENCEL™ Lyocell, imprégnées de la technologie enVy COPPER® fabriquée au Canada, liée de manière permanente et testée indépendamment pour ses performances antimicrobiennes. L'entreprise privilégie dans la mesure du possible des matériaux naturels, durables et certifiés.

Les tissus enVy COPPER font-ils l'objet de tests indépendants ?

Oui. Les tissus enVy COPPER ont été soumis à des tests en laboratoire indépendant utilisant des normes de test antimicrobien reconnues, notamment les méthodologies AATCC TM100.
