As soon as April rolls around, we’re on a mission to spot the absolute best organic cotton shirts and breezy, organic cotton tank tops for the warm-weather season. 

Can you blame us? This wardrobe staple is as comfy as your favorite pajamas but versatile enough to rock from a casual coffee date to a beach bonfire. 

Going to the gym? Throw on a tank top with a pair of leggings. Exploring a new city? Pair your ethical t-shirts with a maxi skirt and your barefoot sandals. Have a work meeting? Style your tee with a pair of tailored trousers and layer it with a blazer. It’s that easy!

To help you find the ultimate versatile piece, I made a list of the best sustainable t-shirt brands in 2024.

Sustainable T-Shirt Brands for Organic Cotton Shirts & Tanks

Let’s be honest for a second, organic cotton tank tops and t-shirts are very affordable. But, not as cheap as the H&M, Marks & Spencer, or any other fast-fashion tees out there. There’s a darn good reason for that! 

Ethical t-shirts are free from the nasty chemicals and pesticides that conventional cotton usually swims in. As we explained in this guide, regular cotton requires huge amounts of chemical fertilizers and pesticides to grow which heavily impacts the local ecosystems. 

These chemicals can also cause skin rashes and allergic reactions especially if you have sensitive skin.

That’s not even the most shocking fact about the humble cotton tee! To make a single cotton t-shirt, 2,700 liters of fresh water. That’s enough water to quench one person’s thirst for 2.5 years. So, it’s no surprise that the textile industry is currently the third largest source of water degradation and land use. 

Everyone, and I mean everyone, should have at least one organic cotton tee or tank in their arsenal. The fabric is grown without any synthetic pesticides or fertilizers, which means cleaner soil, water, and air. 

Plus, it’s better for the folks living nearby, too – less pollution means healthier communities all around. And thanks to its high-quality fibers and minimal processing, sustainable t-shirts are built to last.

Whether you’re a busy mom on the go, a gym rat sweating it out, or a laid-back dude who just wants to look cool without trying too hard – there’s a place for organic cotton in your life.

7. Organic Basics

sustainable t-shirt brands

As someone who has to deal with polyester allergic reactions pretty regularly, I gave Organic Basicsnatural activewear collection a try earlier this year. Spoiler Alert: I loved it! 

Thus far, I own the “merch boxy tee” which I always layer with the “core” organic cotton crop top and a pair of “lounge shorts.” 

As someone who loves colorful clothing, I picked shades like lavender, and green, which didn’t seem to fade even after I air-dried them under direct sunlight (don’t do that!).

How much did I spend on those 3 items? Under €60. 

This European Certified B Corporation opts for the finest, GOTS Certified, and OEKO-TEX® Certified organic cotton to create ethical t-shirts, sports bras, shorts, and leggings for sensitive-skin folks like myself. 

The company has ethical manufacturing partners all over the world and does its best to minimize waste and resources.

10. Quince

sustainable t-shirts

From sustainable swimwear and sunglasses to flattering, organic cotton t-shirts for women and men, the ethical clothing brand Quince should definitely be on your radar. 

I’d highly suggest checking out both their cotton modal sustainable t-shirts and their 100% organic cotton t-shirts. 

These two collections feature the same GOTS organic cotton fabric that’s perfect for layering up with sweaters and jackets or whenever it feels like a tee-and-jeans day. 

You can learn more about the benefits of modal here – it’s basically a semi-synthetic textile made from cellulose from beech wood. 

What’s more, Quince is very transparent with their supply chain, manufacturing process, and prices.

They explain exactly how they manage to keep their prices low, even if they use top-quality fibers and pay workers a good wage.
