Quality Quality Most manufacturers use petrol (plastic) inks which stick to the surface of the T-shirts. These inks create a rough surface and contain toxic phthalates. But our T-shirts are different! They are printed with the finest water-based inks, which guarantee a beautiful 3D effect. The colour is spread directly onto the fibres, so it doesn't wash off. Endurance Our shirts are made of 100% pre-washed cotton (even the fiber holding the T-shirt together is cotton). If you follow the washing instructions (cold water, 30ºC) not only the T-shirt keeps its original proportions, but the motif lasts for many years. Health The Mountain products have 100% Oekotex certificate (one of the highest standards in the world) which guarantees that the T-shirts don’t contain any chemicals harmful to the human body. The Environment Our T-shirts are printed with water-based colours and inks which are enviromentally friendly. All manufacturing processes ensure the protection of our Earth, air and water.
