Organic cotton: why we make our tall T-shirts from it

Organic cotton is soft, breathable and grown without pesticides. We’ll explain what makes it special, what the GOTS and OEKO-TEX certificates mean and why we make our elongated T-shirts, hoodies and sweatpants from it.

In short

Organic cotton, also called bio cotton, is grown without pesticides, and its production is overseen by the international GOTS certification. Our cotton also has OEKO-TEX Standard 100 certification, so it suits even very sensitive skin. We use long-staple cotton with a small amount of elastane: it’s soft, doesn’t pill and keeps its colour and shape. We make our T-shirts, hoodies and sweatpants from it in Czechia. Wash them inside out at 30 °C and don’t put them in the dryer.

To make our products, we chose the path that puts as little strain on the environment as possible. That’s why we use organic cotton, also known as bio cotton. It’s soft, breathable and pleasant to the touch from morning till night. Come and see everything that goes into it.

What is organic cotton?

On top of that, we choose long-staple cotton, which is incredibly soft, breathable and durable at the same time. The result is clothing that feels pleasant on your body and is kinder to nature.

Why do we make elongated T-shirts from organic cotton?

Because we want you to feel good in your T-shirt all day and for it to last. Organic cotton is soft, breathable and pleasant, so when you wear a T-shirt under a hoodie, you won’t even notice it. The fabric doesn’t pill, keeps its colour and shape, and the long fibres make it durable. On top of that, we add what tall people need most: an elongated cut. For most of our elongated T-shirts, you choose from three lengths, Classic, Long and Extra Long, and two fits, Slim and Regular. Thanks to the minimalist look, it’s easy to combine with anything.

What do the GOTS and OEKO-TEX certificates mean?

For cotton to be labelled organic, it has to meet strict criteria. Our organic cotton has two certifications:

Certificate What it confirms
GOTS (Global Organic Textile Standard) an international standard for the eco-friendly production of textiles from organic fibres, a guarantee of pure organic cotton produced under ethical and ecological conditions
OEKO-TEX Standard 100 the fabric is suitable even for very sensitive skin

Only natural resources and environmentally safe processes are used to produce the cotton, and the people on the farms work in decent conditions. Thanks to both certifications, you can be sure about what you wear right next to your skin.

Why is there elastane in the cotton?

To help our T-shirts keep their shape and length, we add a small amount of elastane to the organic cotton. It makes the fabric stretchy and comfortable, whether you’re sitting in the office or on the road, and the T-shirt keeps its shape even after washing.

What do we make from organic cotton?

From organic cotton we make elongated T-shirts with short and long sleeves, tank tops, hoodies (crew neck, hooded and zip), sweatpants and sweat shorts. For women, you’ll find long T-shirts, hoodies and sweatpants.

Piece Why you’ll like it
T-shirts lighter fabric for summer and for layering under a shirt
Hoodies heavier fabric, the brushed inside keeps you warm
Sweatpants heavier fabric, brushed inside and a comfortable elastic waist

You’ll find the whole range in the organic cotton clothing for tall people category, and separately in men’s hoodies and men’s sweatpants.

Where is our organic cotton clothing made?

We make our organic cotton T-shirts, hoodies and sweatpants in Czechia under fair conditions. We spent long months fine-tuning every detail together with Czech seamstresses who share our values of ethical production and quality. That’s why you’ll find them labelled Made in Czechia on the product pages. Just for completeness: the chino trousers in our range are made in a Portuguese workshop that has specialised in trousers for generations. You can read more about how our clothing is made in the article How TallGuys clothing is made.
