How Merino keeps you warm in the cold
Staying warm is all about trapping as many pockets of air next to your body as possible and that’s what Merino is built for. Every Merino fibre is hollow which means you have millions of air pockets trapped next to your skin. And as the natural curl of wool fibres traps more air than straight fibres, the microscopic texture of the fabric itself will also retain heat. The t shirt’s engineering comes into its own in cold terrain. It’s soft, stretchy and high wicking so you can wear it on its own if you’re looking to go fast and light.
Fast drying and insulating even when wet
The outside of every Merino fibre is covered in a natural wax coating which makes it water repellent when you’re outside. At the same time the Merino acts like a sponge to soak up sweat and spread it over a massive surface area so that it evaporates at high speed. And as Merino can absorb over 30% of its own weight in water and still feel dry, you’ll stay warm and insulated.
Merino keeps you cool in the heat
Merino also stops you overheating in higher temperatures as it simply releases its warmth if you’re getting too hot. Merino wool has to keep sheep cool even when the temperature goes over 30°C, so the Merino fibre naturally absorbs the moisture from sweat and disperses it to start releasing heat.
Stretches with you, whatever you’re doing
We built our fabric from scratch in Portugal with one of the softest substances in the world. These same Merino fibres are naturally elastic which means the Planet Earth T Shirt will stretch with you whatever you’re doing. They can also be pulled with a lot of sudden force without breaking and still return to their original shape.
Built from the same Merino sheep, but a more regular fit
When it comes to sizing there aren’t any rules. Every company in the world is a little different. Most of our t shirts have been quite a slim fit so far. And it’s because our first ever t shirt was our super tough Ceramic T Shirt which was designed to be worn quite close to your body to help keep your skin on. But now we’ve got more t shirts. And they’re made from lots of different materials like carbon fibre, black algae, pulped eucalyptus, and Merino. So we’re rebuilding them all with a more regular fit. Starting with our Planet Earth T Shirts.
It’s hard to make a Planet Earth T Shirt smell
It’s not sweat that smells, or even the clothes themselves, it’s the build-up of bacteria on the surface of the clothes. Merino is naturally odour resistant – odour molecules are absorbed and locked into the centre of the fibre of the Merino so you simply can’t smell them. They’re then released when you wash the t shirt.
Why our Merino wool comes from Australia
Flocks of Merino sheep have been kept for their wool ever since the 12th century. Bred by the Spanish royal family they were so highly prized that taking one out of the country would have you killed. And when the first 26 sheep from the royal flock sailed to Australia in 1797, even the ship’s crew gave up their cabins so the sheep could have them. While half the sheep died on the crossing, the rest became the start of a breeding line that would go on to dominate modern Merino production.
Built for wherever you call home
There are over 510 million square kilometres on the surface of Earth, and our Planet Earth gear is designed to work in every single one of them. Alongside our Planet Earth T Shirts you’ll find Planet Earth Pants and Planet Earth Shirts. With magnetic storm flaps, reinforced anti-mosquito collars, hidden passport pockets for hostile environments, shatterproof buttons and built in air-con, they’re built to work in every mangrove swamp, arctic plateau, desert or office on Earth.
