OTSO t-shirts, the most breathable and lightest on the market

Spring is already in full swing in many parts of the world, and most runners are already going out in short sleeves to enjoy the sport they love most.

Whether on asphalt or in the mountains, more and more runners seek lightness and comfort. And since 2019, when we launched our first shirt on the market, many thousands of people around the world have been able to enjoy our quality:

• Super light, the lightest in the running world.
• Super breathable thanks to its “honeycomb” fabric, which expels sweat from the body to the outside.
• Elastic both horizontally and vertically, providing an incredible feeling of comfort.
• And, of course, with hundreds of designs for every taste.
• Made in Europe with the highest quality standards
