Sustainable Silk™

Sustainable Silk is a blend of 31% Silk and 69% Naia™, treated with Schoeller bluesign® certified stain repellent technology.

That means you can wear your silks and everyday stains will no longer get in the way. And they are completely machine washable.

Contemporary Cotton

Contemporary Cotton is a high-performance fabric that moves moisture away from the body.  It keeps you cooler and drier.  And washes clean of odors.  The unique construction of Contemporary Cotton combines absorbent and repellent cotton yarns.  This allows moisture to be wicked and absorbed away from the body, while preventing it from moving through to the outer garment. 

Each Essential Undershirt is enhanced with a Contemporary Cotton gusset in the underarm. This gives you extra sweat protection while keeping you dry and comfortable. And keeps your clothes clean longer.


Gentle on skin. Long lasting. Breathable.
TENCEL™ is a sumptuously soft thermo-regulating fabric. It is sustainable and biodegradable. The fibers are sourced from natural raw materials and processed in a closed-loop production process. This process recycles water and reuses the solvent at a recovery rate of more than 99%, drastically reducing the impact on the environment. TENCEL™ fibres are also certified as compostable and biodegradable.
