The Serene Sling is certified Oeko-tex Standard 100.
But what is Oeko-Tex?

Oeko-Tex is an exacting procedure and certification system that tests for over 100 harmful substances. It tests for substances that are used throughout the manufacturing procedure of a product and makes sure that the product you buy is not only healthy for you but also friendly to the environment. Oeko-tex is widely recognized in Europe and slowly becoming popular with well-known retailers in the United States.

What kind of harmful substances does Oeko-Tex check for?

Oeko-Tex tests for over 100 unsafe substances, including formaldehyde. Formaldehyde is particularly harmful to children and has been known to trigger allergies and asthma attacks. Oeko-Tex recognizes this and requires that all textiles certified by Oeko-Tex must register 0.01 parts per million (ppm) or less. Serene Sling met this requirement as part of the Oeko-Tex certification, proving that our product is safe for you and your baby to enjoy.

What does Oeko-Tex mean for Serene Sling?

Oeko-tex testing makes sure that everything that goes into making the Serene Sling, from the fabric to the thread to the tag, was ecologically manufactured without the use of harmful substances.
