At Calcetinos, we prioritize your health, and that's why the yarn we use to make our products is certified under the strictest standards on the market.
What is the Oeko-Tex Standard 100 certificate?
The OEKO-TEX® STANDARD 100 certification is one of the most recognized eco-labels in the textile sector worldwide. This certification guarantees that every component of a product—every single thread in our socks—has been tested for more than 300 harmful substances .
Unlike other more general certifications, the Oeko-Tex Standard 100 seal focuses on consumer safety : it ensures that the material that comes into contact with your skin is completely safe. According to the Oeko-Tex® organization itself, in many cases the required limit values are even stricter than national and international legal requirements.
Bottom line: When you see this label, you know the material has been tested in independent laboratories and you can trust its quality.
Product classes certified by Oeko-Tex
Not all textiles require the same level of quality. Therefore, the Oeko-Tex Standard 100 certification is divided into four classes:
- Class I : articles for babies and children up to three years old (underwear, bedding, towels, diapers, etc.).
- Class II: Products in direct contact with the skin, such as T-shirts, underwear or socks.
- Class III: textiles without direct contact with the skin, for example jackets or coats.
- Class IV: decorative materials, such as curtains, upholstery or tablecloths.
👉 In this case, the threads used to make our compression socks are Class II certified , the most important class for garments worn in direct contact with the skin for hours. This guarantees comfort, safety, and confidence with every use.
Why is it important that the materials in your socks have this certification?
The Oeko-Tex Standard 100 certification isn't just another seal: it has a direct impact on your health and sustainability. Here are some of its benefits:
- 👣 Safe for your skin: Avoid toxic substances, harmful dyes, or irritating finishes.
- 🧪 Proven confidence: Tests are performed in independent laboratories and renewed annually.
- 🌱 Environmental responsibility: a cleaner production process with less environmental impact is encouraged.
- 🛡️ Long-term prevention: Using certified products means reducing the risk of allergies, irritations, or health problems related to chemicals.
In other words: when you choose socks made with Oeko-Tex-certified materials, you're not just looking for comfort, but also peace of mind.
Difference between Oeko-Tex and other eco-labels
It's common to confuse Oeko-Tex with other textile certifications such as GOTS (Global Organic Textile Standard) or "eco-friendly" labels. The main difference lies in the focus of analysis:
- GOTS focuses on fibers sourced from organic crops and ensuring sustainable processes.
- Eco-friendly is a generic term that does not always imply exhaustive control.
- Oeko-Tex Standard 100 , on the other hand, certifies that the final product has been tested for harmful substances and is safe for the consumer.
Therefore, Oeko-Tex Standard 100 and GOTS are not mutually exclusive, but rather complementary: one ensures the origin of raw materials, while the other protects the end user.
Oeko-Tex certified companies and why Calcetinos materials are among them
Thousands of textile companies around the world trust Oeko-Tex to guarantee the safety of their products. Being part of this group means complying with a strict, annually auditable protocol.
In the case of Socks, the Oeko-Tex Standard 100 certification endorses our commitment to your health and well-being: our socks are made with materials free of harmful substances and are safe for prolonged use during activities such as hiking, running, or everyday life.
What does Oeko-Tex Standard 100 mean?
That a textile has been tested for more than 300 harmful substances and meets stricter limit values than the legal ones.
Is it the same as organic clothing?
No. Organic clothing certifies the origin of the fibers, while Oeko-Tex guarantees that the final product does not contain harmful substances.
