Organic Underwear FAQs
What material is best for underwear? Natural, breathable fibers are best. Synthetic fabrics like nylon and spandex trap moisture, which can lead to bacterial or yeast infections. Organic cotton is ideal - it’s grown without pesticides or harmful chemicals, making it non-toxic and safe for your skin. Bamboo and hemp are also great moisture-wicking alternatives.
Which are the best brands to buy organic cotton underwear from? There are lots of great options out there, but we like Subset, Pact, and KENT in particular as they create 100% organic cotton underwear.
What’s the difference between organic cotton and regular cotton? The main key differences between organic cotton vs conventionally grown cotton is the way it is grown and treated.
Conventional cotton uses up to 11 times more water to produce than organic cotton. Up to 80% of organic cotton is watered using rainfall, rather than groundwater irrigation.
Organic cotton is also grown without the use of toxic pesticides and harmful chemicals. These chemicals can leech into the land and cause land and water pollution.
Organic cotton farmers usually use natural pesticides such as insects.
What does GOTS stand for? GOTS is the abbreviated term for the Global Organic Textile Standard certification.
A textile product carrying the GOTS label must contain a minimum of 70% certified organic fibres. Whilst a product with the label grade grade ‘organic’ must contain a minimum of 95% certified organic fibres.
What is Oeko-tex? OEKO-TEX® is an international organization that sets standards to ensure products that carry the label don’t contain harmful levels of chemicals or hazardous substances. The certification is given by OEKO-TEX® to a textile brand when their product meets the strict testing and certification process. So, as a consumer, when we see the Oeko tex label, we know that a product doesn’t contain high levels of harmful substances or chemicals and is thus safe for humans and the environment.
