Sustainable Staples: The Best Organic Cotton T-Shirt Brands

The T-shirt is a cornerstone of modern menswear, but the cotton industry is problematic. Here’s how switching to organic could reduce your environmental impact

Words by: Paddy Maddison

It’s impossible to imagine a garment more integral to modern menswear than the humble T-shirt. This simple short-sleeved top is something that almost everyone owns, regardless of age, culture, perceived social class or tax bracket. If you’re a human being born within the last century, chances are you’ve bought at least one over the course of your life. Probably a lot more than that.

The T-shirt may be the bedrock of contemporary casualwear, but its ubiquity comes at a price. It’s no secret that the fashion industry is one of the planet’s biggest polluters. What might surprise you more is that a significant portion of that pollution and environmental damage comes specifically from the production of cotton… you know, the stuff that all of your tees are made from.

So, what’s the solution? Switch to merino or rayon? Stop wearing T-shirts altogether? Thankfully there’s an alternative in the form of organic cotton. It looks like standard cotton, feels like standard cotton, performs like standard cotton, but its production is a lot kinder to the planet and it’s made without the use of nasty chemicals. Here’s what you need to know.

What is organic cotton?



Organic cotton is the same as regular cotton in every way other than its production. All of the components used to make it come from the earth, which means no harmful chemicals, genetic modification or synthetic substances.

Instead of chemical pesticides, organic cotton farming relies on techniques such as using organic fertilisers, utilising insects, rotating crops and relying on human labour to keep weeds under control.

Any dyes used are natural and sustainable, and bleaching is done without the use of chlorine.

So, organic cotton or regular cotton – which one is better? Well, in purely environmental terms, organic cotton is the clear winner. To understand why, the best thing is to take a closer look at regular cotton and how it’s made.

When we think of genetic modification, it’s usually food that first comes to mind. Things like fruits and vegetables that have been artificially altered to grow a certain way. But genetic modification isn’t unique to food. In fact, cotton is one of the top four genetically modified crops on the face of the planet.

On top of that, cotton is also known as the world’s dirtiest crop. Its production requires huge amounts of toxic chemicals like pesticides and fertilisers, which poison people and animals, as well as polluting the environment. Many of these pesticides are some of the most dangerous in the world. In fact, the cotton industry eats up almost a quarter of all environmentally harmful insecticides sold worldwide.

Organic cotton, on the other hand, is produced using only natural substances. Because of the reduced amount of harmful chemicals involved, organic cotton is better for the planet, safer for textile workers and better for cotton farmers.

What makes a great organic cotton T-shirt?

So, we’ve established that organic cotton is the way forward if you want to make your T-shirt consumption habits more sustainable, but what should you be looking out for when buying one?

Many brands producing organic cotton T-shirts have things like supply chain and pricing transparency, which makes buying organic even more appealing. Keep scrolling to learn more about what to look out for.

Transparent pricing



Pricing transparency is something a lot of sustainable brands now have on their websites for every product.

It’s a breakdown of what goes into making and transporting a piece of clothing, showing how much the process costs the label, and often offering detailed information about factories and countries of manufacture.

This tells you whether or not your money is being well spent, and gives a clear indication of workers’ conditions to help you make an informed and conscious purchase.

Ethical manufacture



A good brand that cares about its workers will have its clothes made in reputable factories that have proven track records of treating their staff well.

Make sure to take a good look at the website to make sure your money is going where you want it to.

Fully recyclable



T-shirts made from 100% organic cotton are completely biodegradable and infinitely recyclable. This is one of the many great things about them.

Check that the garment hasn’t been made with any synthetic fibres. If it has, it may not be quite so straightforward to recycle.
