THE NEW STANDARD IN ACTIVEWEAR: PLANT-BASED FABRICS, NON-TOXIC DYES, AND SKIN-SAFE PERFORMANCE YOU CAN TRUST.
LENZING MODAL
Our CORE fabric is made with Lenzing Modal™ fibers.
Naturally soft and smooth to the touch, Lenzing Modal™ is the best alternative to polyester and nylon for activewear.
These fibers are made from wood — a renewable raw material carefully sourced from responsibly managed forests. For every tree used, growth is balanced with regeneration to ensure this valuable resource remains for the future.
Certified by OEKO-TEX® Standard 100, our fabric is free from harmful toxins and safe against your skin.
TENCEL™ is a trademark of Lenzing AG.
ORGANIC COTTON
Cotton is a natural fiber valued for its breathability and softness, making it a great organic alternative to petroleum-based fabrics.
Using organic cotton instead of regular cotton has the potential to build soil health, as it is grown without the use of synthetic fertilizers.
We prioritise certifying the finished product with internationally recognised standards including GOTS (Global Organic Textile Standard).
CERTIFICATIONS
Certifications are part of our promise of transparency. They give you confidence that every Glas Active piece is safe, sustainable, and made to the highest standards.
OEKO-TEX® Standard 100
This certification guarantees our fabrics are free from over 1,000 harmful chemicals, or that any trace amounts fall well below strict safety limits. Recognized worldwide, OEKO-TEX® Standard 100 is one of the most trusted labels for textile safety — giving you confidence that Glas Active pieces are skin-safe and toxin-free.
Global Organic Textile Standard (GOTS)
The GOTS label is the world’s leading certification for organic textiles. It guarantees our cotton is grown without synthetic fertilizers or pesticides and produced under strict environmental and social standards — so every Glas Active piece meets the highest level of organic integrity.
USDA Certified Biobased Product
This certification confirms our fabrics are based on renewable, plant-derived resources rather than petroleum. Recognized by the U.S. Department of Agriculture, it highlights our commitment to using natural, biobased materials while minimizing reliance on crude oil–based fibers.
Medically Tested – Tested for Toxins
This certification ensures our fabrics are safe for your skin and your health. They’ve been tested to confirm they don’t release harmful substances or cause irritation — giving you peace of mind that Glas Active is as gentle as it is effective.
Biodegradability and Compostability
Lenzing Modal™ fibers are certified by TÜV Austria as both biodegradable (in soil, freshwater, and marine environments) and compostable (in home and industrial settings). At the end of their life cycle, they can safely return to the environment without leaving harmful residues behind.
