Frequently Asked Questions

Which are the best brands to buy organic cotton underwear from?

There are lots of great options out there, but we like Knickey, Pact, and Organic Basics 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.
