The Best Comfy & Organic Cotton T-Shirts
Ah — the classic t-shirt. Great for dressing up, dressing down, or just lounging around. Everyone already has this fashion essential in their closet, but there’s a good chance that the average t-shirt isn’t meeting the mark when it comes to sustainability. So if you’re in the market for a better T-shirt that’s more gentle on the planet, let’s take a look at some of the best organic cotton T-shirt brands on the market today.
Why organic cotton?
Since t-shirts are seemingly so simple, you might wonder why they’re not all the same. The truth is, conventional cotton can contribute to environmental degradation and unethical practices in many ways.
For one, ordinarily-grown cotton requires a large amount of pesticides and insecticides that can seep into the environment and affect both workers and nearby plants and animals. An example of this is seen inbutterfly declinein agricultural areas with heavy pesticide use. Cotton also requires an incredible amount of water to produce, in part due to pesticide use and ineffective farming practices.
In contrast, regenerative agriculture and methods used to grow organic cotton use significantly less water while also reducing the amount of runoff that normally pollutes streams and waterways. Another important reason to choose organic cotton is because, like many of the brands on this list, most organic products also use fair-trade labor resources. This means that farmers and other people in the production line are paid and treated fairly, which is especially important in such a labor-intensive industry such as cotton.
One unexpected benefit of organic cotton is that it’s often more durable and long-lasting, both because the cotton itself is healthier when it’s picked and because the cotton doesn’t go through a ton of bleaching and other processing methods that can minimize the material’s integrity.
Therefore, if you’re looking for a t-shirt that has a better impact on the environment, you’ve come to the right place. And, since tees are so simple and often on the cheaper side compared to other sustainable clothing, this is a great place to start if you want to update your wardrobe to be more eco-friendly.
