Short answer: TENCEL™ is lyocell. They're the same material. TENCEL™ is simply the brand name that Lenzing AG — an Austrian fibre manufacturer — uses for the lyocell they produce.
That said, the distinction does matter, and understanding it helps you know what you're actually buying when you see either word on an activewear label.
What is lyocell?
Lyocell is a cellulosic fibre made from wood pulp — typically from eucalyptus, beech, or oak trees grown on sustainably managed land. The wood pulp is dissolved in a non-toxic solvent and spun into fibres. Unlike rayon or viscose (older wood-based textiles), lyocell is made in a closed-loop system that recovers and reuses over 99% of the solvent, making it one of the most environmentally responsible textile production processes available.
The result is a soft, breathable, moisture-absorbent fibre that is biodegradable, free of microplastics, and significantly better for the environment than polyester. More on how it compares to polyester here.
What is TENCEL™?
TENCEL™ is a trademark owned by Lenzing AG, one of the world's leading producers of wood-based fibres. When you see TENCEL™ on a label, it means the lyocell was produced by Lenzing, using their specific production standards, with verified sustainable forestry sourcing.
Lenzing was one of the pioneers of the closed-loop lyocell production process and has been producing lyocell commercially since the 1990s. Their production is certified by OEKO-TEX, FSC (Forest Stewardship Council), and other standards that verify both environmental and social responsibility throughout the supply chain.
So are TENCEL™ and lyocell the same thing?
Yes and no.
All TENCEL™ is lyocell. But not all lyocell is TENCEL™.
Other manufacturers also produce lyocell — the fibre type itself is not proprietary. The difference is that TENCEL™ comes with Lenzing's quality controls, certified sustainable forestry, and verified production standards. Generic lyocell may be produced under very different conditions with significantly less environmental oversight.
This matters for two reasons:
- Quality consistency: TENCEL™ fibres have tighter specifications, which means the fabric performs more consistently in terms of softness, moisture management, and durability.
- Verifiable sustainability: If a brand says "made with lyocell" without specifying TENCEL™ or another certified producer, the environmental credentials are harder to verify.
TENCEL™ lyocell for activewear
TENCEL™ lyocell has specific properties that make it well-suited to activewear:
- Moisture absorption: Lyocell absorbs around 50% more moisture than cotton, managing sweat by drawing it into the fibre rather than leaving it on the skin's surface.
- Odour resistance: The smooth fibre surface doesn't give odour-causing bacteria anywhere to lodge — unlike polyester, which traps bacteria in its synthetic structure and develops permanent odour over time.
- Softness: TENCEL™ lyocell is noticeably softer than polyester and most synthetic activewear fabrics, which matters for long training sessions and skin-contact garments.
- Breathability: Good airflow through the fabric — important in warm-weather or high-intensity training.
- No microplastics: Unlike polyester, lyocell sheds natural cellulosic fibres that biodegrade, not synthetic microfibres that accumulate in waterways and food chains.
Why APRÍ uses TENCEL™
APRÍ uses TENCEL™ certified lyocell specifically because of the verified production chain. The brand's position on fabric — lyocell over polyester — is grounded in the environmental and performance properties of the fibre. Using TENCEL™ rather than generic lyocell means those claims are verifiable, not just marketing copy.
APRÍ's TENCEL™ lyocell garments are also finished with plant-based anti-odour technologies — NordShield™ (APRÍshield™) and HeiQ Mint™ (APRÍtech™) — that work with the fabric's natural properties rather than against them.
The bottom line
TENCEL™ and lyocell are the same material. The distinction that matters is between certified TENCEL™ lyocell (Lenzing, verified sustainable production) and uncertified generic lyocell (variable standards, harder to verify). When APRÍ says lyocell, it means TENCEL™.
If you want to dig further into whether lyocell is actually better for working out — including a direct comparison against polyester on performance, odour, and environmental impact — that comparison is here.
