The Iron Roots performance (PF) 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 wood-based fibers 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 176 cm / 5'9" and is wearing size S.

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

This t-shirt is made from a durable mix of 50% TENCEL™ Modal and 50% organic cotton, which has been processed into a custom single jersey fabric. This fabric and design combination is called PF25.Wood.

All of our products are made with materials from natural origin, 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.
▪ Fabrics from natural origin can shrink a little bit after washing them, which we have taken into account with our sizing.

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.

This material is sourced from European FSC certified forests, where 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.

This product and the dyes used to create it are both OEKO-TEX certified, which means that it has been thoroughly tested for harmful chemicals throughout the supply chain. That is how we create healthy, BPA-free sportswear.

Great T-shirt

The T-shirt's fabric feels sturdy but also soft and stretchy at the same time. I love the perfect fit and the blue colour. I wish there were even more colours to choose from.

Fijne zachte stof

Fijne zachte stof. Een keer mee hardgelopen. Zat goed en heel ademend.

Zit heerlijk

Heel blij met deze aankoop! Ik had dit shirt al in het groen en omdat het zo lekker zit en ook beter is voor de wereld dan andere sportshirts, heb ik er nog meer besteld.

Echt verantwoord?

Prachtig sportsters en draagt heerlijk. Ik was blij dat er eindelijk sportkleding ontwikkeld is van natuurlijke materialen. Wel vraag ik mij af of de grondstof vanuit de eucalyptusboom echt verantwoord is. Volgens mijn informatie horen deze bomen in Portugal niet thuis, nemen veel water en zijn verspreiders van vuur bij de vele bosbranden. Hopelijk kunnen jullie dit weerleggen……..

Beste Joke,

Bedankt voor je bericht. Fijn dat je blij bent met het t-shirt en goed dat je zulke vragen stelt! Je mag dit soort vragen uiteraard ook gewoon mailen naar ons :).

Wat betreft de eucalyptusbomen die wij gebruiken, deze komen met name uit Oostenrijk rondom te fabriek van Lenzing (die onze vezels maakt). Wel zijn de t-shirts in onze Portugese fabriek in elkaar gezet met deze vezels uit Oostenrijk, wellicht dat we dat wat duidelijker moeten communiceren.

Het is waar dat deze bossen een risico kunnen vormen voor bosbranden, maar mits ze goed beheerd worden (door bijv. een FSC label te hebben) wordt dit risico kleiner. Daarnaast wordt het bos ook steeds verjongd (nieuwe bomen worden gepland voor gekapte bomen), waardoor er meer CO2 opgenomen kan worden.

Geen enkele oplossing is perfect en er zullen altijd ons best doen om te verbeteren waar we kunnen, maar voor nu zijn wij tevreden met deze grondstof (mits uit de juiste bron verkregen).

Mocht je verder nog vragen hebben, laat het gerust weten :).

Met vriendelijke groet,


Noor Van Dijck - van Bergen
Fantastisch shirt!

Mooie kleur, fijne pasvorm, voelt zijdezacht aan. En het mooiste: het stinkt absoluut niet naar zweet, na intensief sporten! Ik kan het iedereen aanraden.
