Fabric & Quality

100% Organic Cotton

All ONROIT t-shirts are made from 100% cotton.

Cotton is a natural, breathable fiber known for its softness, durability, and comfort. It allows airflow, absorbs moisture, and feels comfortable against the skin — making it ideal for everyday wear.

We use standard-weight fabric that balances structure and comfort, ensuring the garment holds its shape while remaining easy to wear.

GOTS-Certified Organic Cotton

Our cotton is certified under the Global Organic Textile Standard (GOTS).

GOTS is the leading global standard for organic textiles. It ensures:

• Organic farming practices without harmful chemicals

• Environmentally responsible production

• Strict social criteria throughout the supply chain

• Full traceability of materials

This certification guarantees that the cotton used in ONROIT garments meets high environmental and ethical standards from raw material to finished product.

Embroidery Quality

Each design is finished with precision embroidery.

Embroidery provides:

• Long-lasting detail

• Resistance to washing and wear

• A structured and premium finish

• A clean, refined aesthetic

Unlike printed graphics, embroidery adds depth and durability while maintaining a minimalist look.
