WHY WE START WITH TENCEL™
At THRĒ Aktiv, every design begins with intention — and that intention starts with our choice of TENCEL™ Lyocell.
Derived from renewable botanic sources, this natural fiber represents our commitment to materials that perform without compromise.
• A botanical fiber derived from sustainably sourced eucalyptus
• Created through a closed-loop process that recovers over 99% of water and solvents
• Engineered by nature to move with the body — soft, breathable, moisture-balancing, and naturally odor-resistant
• Ideal for skin-close wear, supporting comfort and daily performance without compromise
Our Foundation
THRĒ AKTIV is grounded
in three core pillars
Body. Biology. Design.
Body
Supporting movement, comfort, and modern performance.
Biology
Thoughtfully chosen fibers designed through an endocrine-conscious lens.
Design
Elevated silhouettes where function meets beauty.
Rooted in Nature
Non-toxic. Designed to Be Worn Close.
Comfort & Performance
TENCEL™ Lyocell is considered a non-toxic fiber and is OEKO-TEX® STANDARD 100 certified.
For Natural Harmony
Produced in a closed-loop system, the process uses a single organic solvent that is largely recovered and removed before the fiber is formed.
Why it matters
Activewear sits closest to your skin — under heat, sweat, and movement.

HOW TENCEL™ LYOCELL IS MADE
At THRĒ Aktiv, every design begins with intention—and that intention starts with our choice of TENCEL™ Lyocell. Derived from renewable botanic sources, this natural fiber represents our commitment to materials that perform without compromise.
Responsibly sourced
Wood is harvested from certified, sustainably managed forests.
Gently dissolved
The pulp is transformed using a recyclable, organic solvent.
Converted to pulp
The wood is broken down into natural cellulose.
Finished into fabric
Fibers are washed, spun into yarn, and knit into the materials you wear.
The Collection
The Constance Capsule
Constance means steadfastness quiet strength, resilience, and a reminder to remain anchored in what matters most, even in uncertain times.
Dedicated in loving memory of my cousin Connie.
Born From Healing. Built With Intention.
THRĒ Aktiv was created from a deeply personal healing journey and a simple belief: what we wear should support the body not compromise it.

Our Certifications
GOTS-Certified Facility
(Global Organic Textile Standard)
Our garments are produced in a GOTS-certified manufacturing facility, one of the world’s most rigorous standards for organic textiles. GOTS certification verifies that facilities meet strict environmental and social criteria throughout the production process, including responsible chemical management, wastewater treatment standards, fair labor and safe working conditions, and traceability and transparency in textile processing. This certification helps ensure that fabrics and garments are produced in a way that respects both people and the planet.
OEKO-TEX® STANDARD 100
OEKO-TEX® STANDARD 100 certification verifies that textiles have been tested for harmful substances and chemicals that could impact human health. Every component of the fabric — including yarns, dyes, and finishing processes — is tested against strict global safety limits for substances such as heavy metals, pesticides, formaldehyde, and certain endocrine-disrupting chemicals. This certification ensures that the fabrics used in THRĒ AKTIV garments are safe for direct contact with skin.
Responsible Fiber Sourcing
Our TENCEL™ Lyocell fibers are derived from wood sourced from responsibly managed forests certified by organizations such as the Forest Stewardship Council® (FSC®). These standards help protect forest ecosystems, biodiversity, and sustainable forestry practices.
