The Real Sweatshirt

Get anything you expect from a sweatshirt. Stay cosy and warm in any weather. Enjoy sweat-wicking and temperature regulation if you perform at your limits. And look chic - no matter if you are in the spotlight or crashing on the couch. Our french terry merino wool sweater is a versatile companion, featuring our very own 100% merino wool loopback (330g per square meter), triple stitching and plastic-free cuffs. Made earth-positive by our passionate creators in Germany and Portugal.


We're rewinding history with our loopback sweatshirt made from pure merino wool. In 1930 Benjamin Russell introduced the cotton sweatshirt to replace scratchy wool sweaters in sports. The material was a fine knit on the outside and loops similar to terry cloth on the inside, which are soft on the skin and supposed to wick sweat.

Almost 100 years later, we have developed an authentic 330-gram loopback made from the finest merino wool, which can only be distinguished from a cotton sweat fabric by its exceptional function when worn. The yarn on the inside is exceptionally soft and scratch-free, and on the outside, we use more robust wool so that our shirt can accompany you on every adventure.

For the first time, you can speak of a sweatshirt because our wool is not only soft but also highly breathable, temperature-regulating and moisture-wicking. And, of course, antibacterial. So ideal for sports.

We reinforced all stressed seams with a triple-cover stitch. Finally, for best functionality, we've developed a robust 2x2 rib for the cuffs made from 100% merino wool - completely plastic-free. Its elasticity is fascinating, and it completely retracts into shape when regenerating.

Raw Material: 100% Super Fine Merino Wool from Australia, 17.2 microns inside, 20 micron outside, mulesing-free
Yarn: Nm 80/2, S twist and Nm 60/2, S-twist
Fabric: Loopback (French Terry), 330g/m2
Collar: 2x2 rib knit, 55g0/m2
Dyeing: Reactive piece dyeing

Benefits of our Merino Wool

  • Merino wool is antibacterial and prevents odours. Air it out after each wear and it regenerates.

  • Merino keeps your skin climate in control with its natural ability to cool or heat.

  • Merino fibres look like a spiral spring. Therefore it's almost not wrinkling and hangs out itself.

  • Our wool is superfine and soft. Completely itch free. You won't find more comfortable shirts.

Full Transparency

We think transparency is fantastic. It gives you, as a consumer, a better understanding of the value of your purchases and the ability to decide what kind of making you want to support or impede.

So transparency should be the standard, not the exception. It also helps us as a company to understand where we still lack knowledge. So hopefully, in the end, this enables us to provide you complete transparency on every step from farm to factory, the cost of our garments and the impacts our business has on people and planet.
