Fit guide: The Carbon Fibre T Shirt is slim fitting. If you’re on the borderline between two chest sizes or would like a more relaxed fit as shown in the photos, we recommend you go for the size up.

Model wears: Trail runner, swimmer and surfer Aljoscha Fábregas is 6ft 1 / 185cm with a 38.5in / 98cm chest and 31in / 79cm waist. As the t shirt is slim fitting, Aljoscha wears the Carbon Fibre T Shirt in size Medium to get a more relaxed fit.

Personalised advice: See our size guide for more advice on sizing, or you can ask us for personalised sizing advice here.

Returns and exchanges: Don’t worry if you order something and it doesn’t fit – we have a free, no hassle 30 day return and exchange period.

From Graphene, to ceramics, to carbon fibre

Making the world’s most resilient, intelligent and adaptable clothing means we often end up re-engineering materials that started life being used for radically different things. We’ve made jackets using graphene, glass, and bio-luminescent material, we’ve built layering systems out of ceramics, hoodies from fireproof aramid fibres, and we’ve designed pants and vests from a material designed to outlive you. Next on our journey is a t shirt woven with carbon fibre.

Carbon fibre didn’t start life as we know it now

160 years ago carbon fibre was being used as delicate lightbulb filaments by Swan and Edison. It wasn’t until the mid 20th century that scientists realised it could be used as a high strength material. In the US carbon fibres were quickly developed to reinforce high temperature plastic components on missiles. And in the UK, the Ministry of Defence patented the production process before licensing it to Rolls Royce to make jet engines with carbon fibre compressor blades.

It’s the atomic structure that makes carbon fibre so strong

A single carbon fibre is a long, super thin strand of material around 0.005mm across and composed almost entirely of carbon atoms. These atoms bond together to form microscopic crystals that line up parallel to the length of the fibre. It makes the atomic structure of carbon fibre similar to graphite and graphene – with sheets of carbon atoms arranged in a regular hexagonal pattern. And it’s the arrangement of the atoms that makes carbon fibre so strong for its size.

Carbon fibre can be 5x stronger than steel and much lighter

The material we know as carbon fibre is made up of thousands of these individual carbon filaments bundled together and protected by a coating. These larger carbon fibres are classified by how much pulling force the fibre can exert without breaking – known as tensile modulus. Whereas steel has a tensile modulus of around 29 million pounds of force per square inch (PSI), carbon fibre ranges from around 30 to 145 million PSI, which is 5x stronger than steel.

Carbon fibre as a composite

Carbon fibres are typically combined with other materials to make a composite. That’s why the classic image of carbon fibre is the black and grey checks on a bike frame or supercar. These are carbon fibres impregnated with a plastic resin and baked to create carbon fibre reinforced polymer. If your t shirt was made from that it would be completely solid, so we’ve done something different.

How we put carbon fibre into a t shirt

As well as being baked into other materials, carbon fibres can also be woven into them to increase their strength. As carbon fibre is thinner than human hair, it only gets its strength when thousands of these tiny fibres are twisted together to form a yarn. And it’s this yarn that we’ve woven into each t shirt. To the naked eye the carbon fibre will look like a series of single threads. But in reality, each one is a rope-like bundle of thousands of carbon filaments bound together.

It offers hardcore protection

You’ll find each Carbon Fibre T Shirt embedded with over 120 metres of carbon fibre strands. While every carbon fibre thread is smooth and soft to the touch, each one has the same strength as steel, helping make the t shirt highly abrasion resistant. The carbon fibre essentially acts like a ripstop to save your skin. And as it’s woven into the t shirt, these threads can’t be scratched off or washed out.

Why abrasion resistance matters

Abrasion resistance is how you measure clothes’ ability to withstand friction and wear and tear. Whether you're lugging climbing rope over your shoulder, you come off your bike on a downhill track, or your bag is shifting up and down on your back on a long run, that’s all abrasion. Wearing highly abrasion resistant clothing gives you the best chance of coming home from an adventure with your clothes and your skin intact.

How carbon fibre compares to ceramics

In 2017 we used ceramics to create the toughest t shirt on Earth – the Ceramic T Shirt. Since then it’s been taken into jungles, battlefields and live volcanoes. The idea for the Carbon Fibre T Shirt was simply to give it something to compete with. The Carbon Fibre T shirt is grey not black, so should absorb less heat. It’s around 10 grams lighter. And where the ceramics are embedded into the surface of the t shirt, the carbon fibre is woven in.

It’s crazily stretchy as well as tough

The more elastane you have in a piece of clothing the more it can stretch. And the last thing you want when you’re pulling any extreme or repetitive move is resistance from your kit. The Carbon Fibre T Shirt has incredible 4 way stretch as it is 36% elastane, so whichever way you stretch, pull or turn, it will simply go with you. It’s normally difficult to make something very tough and stretchy at the same time, but carbon fibre lets us combine toughness with the properties of an elastic band.

Designed for the unknown

Adventure sport is never predictable, so we've created a t shirt that protects you from every angle, rather than second-guessing where you might need it. The entire surface area of the t shirt is abrasion resistant. Every square centimetre has carbon fibre running through it. Which means it doesn’t matter where a rock, a tree, or the passage of time tries to strike, you should be covered.

It’s breathable and lightweight

Our Carbon Fibre T Shirt is breathable and also hydrophilic, which means it will soak up any sweat and get rid of it fast, so you stay comfortable and dry. While the outside is super-resilient, the underside has a soft, silky feel, making it easy to wear all day. And with the top weighing only 170 grams, you're not paying for the abrasion resistance by having to carry extra weight.
