12 Best Organic Cotton Sweatpants To Up Your Lounge Game In 2023

organic cotton sweatpants

What’s there not to love about a great pair of sweatpants? They’re the perfect item of clothing to wear inside and even outside the house. What’s more, good sweatpants are thermoregulatory, meaning they keep your internal temperature steady regardless of how cold or warm you may be. 

Looking for clothes to exercise in? Needless to say, sweatpants are great for that too! They’re designed to soak up your sweat without clinging to your skin and help you warm up your muscles faster.

The downside to conventional sweatpants is their production, which takes a heavy toll on the environment. While cotton is undoubtedly one of the most comfortable materials out there, its production uses up a lot of water, energy, and chemicals—more than most fibers do. The chemicals used to grow cotton harm not only the environment but farm workers as well. Organic cotton, on the other hand, has the same benefits but uses less water and energy to produce similar garments. 

So on that note, let’s take a look at some sweatpants made from organic cotton that are good for the planet and oh-so-comfy for you.

Benefits Of Buying Organic Cotton For The Environment

Organic fabrics are the way to go when it comes to preserving the environment. Organic cotton uses fewer resources while improving soil quality and reducing pollution. 

Regular cotton uses 20,000 liters of water for every kilogram of cotton. In comparison, organic cotton uses 243 liters per t-shirt. 

Organic cotton is made without chemicals, fertilizers, and pesticides. Regular cotton, on the other hand, is the third largest consumer of pesticides in America. It doesn’t stop there. Regular cotton uses so much water that it leads to soil erosion and degradation, a problem that organic cotton does not have.
