Medici - Cosimo Collection Bamboo Performance Boxers - Nero

We stand behind our boxers — and we want you to feel confident trying them. If they don’t beat your old pair for training, comfort, or fit, we’ll give you a full refund.

No returns needed. No hoops to jump through. Just confidence, guaranteed.

At the highest level, getting 1% better can be the difference between winning and losing.
Training properly is essential — and so is having the right support.

If you train and sleep in traditional boxers, you’re already giving up that 1%.
They weren’t built for movement or recovery — that’s why they ride up, twist, and trap heat when it matters most.

The Cosimo Collection by Medici is built for performance.

We set out to design boxers that help athletes perform at their best — in the gym, on the field, or recovering in bed.
Every pair in the Cosimo Collection delivers next-level performance, comfort, and style — without compromise.

Most men sleep in boxers — but almost none are made with sleep in mind. Standard cotton traps heat and bunches up, leading to sweat, discomfort, and broken sleep.

The Cosimo Collection by Medici is engineered for rest and recovery.

Made from breathable AeroFlex Bamboo and designed with anti-ride-up paneling, they keep you cool, dry, and distraction-free all night — helping your body rest and recover the way it should.

The Cosimo Collection is made from 94% AeroFlex Bamboo Viscose and 6% Elastane. This equals an extremely soft and durable pair of underwear that wicks sweat brilliantly.

AeroFlex™ Bamboo – Breathable, moisture-wicking, and temperature-regulating.

AeroFlex™ Anti-Chafe Paneling– No ride-up. No irritation. Just smooth support where it matters.

Tailored Fit– Supportive but never restrictive. Feels custom-made.

If you’ve got an athletic build or more developed quads, we recommend sizing up for a more relaxed fit.
The quad measurement is the most important to check — it's where things usually get snug, especially if you have more developed legs.
