The Iron Roots performance line is meant for any workout that you engage yourself in. From relaxing yoga to intense CrossFit, our plant-based performance line will enhance your experience, with its antibacterial and breathable properties.

The beechwood in this mix fabric makes this t-shirt extremely soft and gives it the antibacterial properties, while organic cotton creates a straight fit. We designed this product to have great freedom of movement while still being tailored around your arms, so it always looks awesome. The cobalt blue colour is inspired by natural shades and fits perfectly with our philosophy.

This t-shirt has a regular fit and is tailored around the arms. If you usually have size M with your t-shirts, you should also pick size M with this one.

Our model is 194 cm / 6'4" and is wearing size L.

You can find our size chart on the top of this page. If you are still unsure which size to go for, you can contact us here.

This t-shirt is made from a durable mix of 50% TENCEL™ Modal and 50% organic cotton.

All of our products are made from natural materials, which don’t need as harsh cleaning treatments as other, synthetic sportswear. We suggest the following care instructions for all of our products, to ensure that they will keep their performance and last longer.

  • Wash at 30 degrees.
  • Don’t tumble dry.
  • Don’t use bleach.
  • Iron with medium heat.
  • Wash with the same colors.
  • Natural fabrics can shrink a little bit after washing them, which we have taken into account with our sizing.

Our plant-based sportswear also has some awesome properties, which are listed below.


This product is designed in our headquarters in The Netherlands. We produce our sportswear locally (within Europe), to ensure sustainability, responsible sourcing, and ethical production. This product is produced at our factory in Greece. Our factory has GOTS and SMETA certifications, and we visit them on a regular basis. Besides that, we work with them to source our raw materials, yarns, and fabrics from European countries, which is something we are very dedicated to at Iron Roots.

TENCEL™ Modal
This material is sourced from European FSC certified forests, where beechwood trees are grown and regrown when they are used to create products. They are then further processed by Lenzing in Austria, which has won multiple awards for their sustainability efforts and who are widely regarded as some of the most sustainable and innovative manufacturers in the clothing industry.

Organic Cotton
Our organic cotton is GOTS certified and sourced within Europe. By having the GOTS certificate, we can ensure that our cotton has been grown responsibly and with ethical circumstances for the people involved in the processing of our organic cotton.

Sustainable shipping
All of our shipments are CO2 compensated, made possible by our partners at The Green Branch. Besides that, we don’t use any plastics in our packaging. To keep our clothing in good condition while they travel to you, we package them in paper-based bags and ship them in cardboard boxes. This means that all of our packaging can be put in the paper bin and recycled. Lastly, we use recycled paper and cardboard wherever we can.

Perfect Workout Shirt

I love the shirt. It fits great, the color is vibrant, and it feels amazing. So happy to have found a workout shirt free of plastic and other man made materials. Can’t wait to buy another in a different color

Een heel fijn shirt voor hardlopen

Ik heb er nu een paar keer in de winter mee hard gelopen en hij bevalt mij prima. Het zit goed en ademtest goed.

Super cosy material

I love the feel of the material, which is so much nicer than synthetic ones. The material is also really good in absorbing sweat for a long time before it starts to smell.

Finally! A proper plastic-free sport shirt

After a long search for a sustainable sport shirt (plastic free), I am very pleased with Iron Roots Beechwood performance shirts. Lightweight, comfortable and good fitting - also long enough to keep your body covered when arms are raised.

Super shirt

Dit shirt is precies waar ik naar op zoek was: duurzaam, comfortabel, "ademt" goed. Al een aantal keer mee gesport en ik hoef nooit meer een ander sportshirt dan een van Iron Roots. Zo comfortabel, heel licht, goede fit, geen geurtjes na het sporten. En laten we eerlijk wezen, het ziet er ook nog eens heel goed uit. Ik heb meteen de groene kleur ook gekocht!
