Planet Earth T Shirt

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.

Wear it as part of our Planet Earth Merino system

This t shirt is part of our Planet Earth layering system which includes our Planet Earth Hoodie and Planet Earth Baselayer. All three pieces of gear are built from Merino and designed to work together to protect you wherever you are in the world. The baselayer is built with a high integrated collar, while the hoodie comes with an integrated collar and hood that can be worn in four configurations and switched rapidly from one to the other. We built the system to help you adapt at high speed and protect you from the heat and cold, as well as dust storms, insects and blizzards.

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.
