Most boxers aren’t built for athletic performance — especially during complex movements like squats, deadlifts, or sprints.

Athletic performance, especially complex vertical or lateral movements, causes traditional boxers to chafe, ride up, and trap heat.
High-level athletes don’t train in them, so why should you?

The Cosimo Collection by Medici is built for the demands of complex athletic movements — delivering anti-chafe paneling and a 3D pouch that stays supportive through high-intensity training.

Built for athletes. Designed to help you train harder, move better, and get 1% better— every single day.

Do you sleep in boxers? 85% of men do — but most boxers aren’t designed for sleeping.

While you sleep, traditional cotton boxers will naturally trap heat — leading to sweating, friction, and ride-up at the inseam.
The result? Broken sleep, poor recovery, and slower progress over time.

To create the best boxers for athletes, we had to fix what traditional underwear gets wrong.
That’s why every pair is made with AeroFlex Bamboo — a breathable, thermoregulating fabric that works with our anti-ride-up paneling to keep you cool and comfortable all night long.

Built for Athletes. Optimised for Recovery.

Performance doesn’t have to come at the cost of style.


Just because our boxers are built for performance and comfort doesn’t mean we’re willing to sacrifice style.

Inspired by the Medici legacy, the Cosimo Collection unites cutting-edge performance with timeless style — because strength should look as good as it feels.

It blends advanced technical features with a timeless, tailored aesthetic to deliver true performance without compromising on style.


Welcome to a new renaissance.

Quiet luxury, built for performance.
