The most advanced everyday boxer ever made
We didn't set out to make another pair of underwear.
We set out to engineer the foundation of men's comfort one that works with your body, not against it. The TestiCool™ Everyday Boxer Brief is built from advanced heat-conductive yarns and ultra-soft modal for unmatched comfort, breathability, and anatomical support.
It doesn't just fit it performs.
Engineered from the inside out
At its core is the TestiCool™ 3D Pouch designed to lift, separate, and support while maintaining constant airflow.
The result is a natural cooling effect that keeps your body's temperature in check hour after hour.
Add the AirlyCool™ Waistband, and you've got a garment that stays dry, stable, and friction-free even through heat, travel, or training.
Antimicrobial. Thermoregulating. Virtually Weightless.
Our silver yarn blend naturally resists odour and bacteria growth keeping you fresher for longer.
You probably won't, but you technically could wear them more than any underwear in the world and they'd still feel clean.
Designed to Stay Put. Built to Move.
Flat-lock seams and adaptive stretch create a barely-there feel with zero irritation.
The leg construction is designed to reduce unwanted movement, improving stability through training, travel, and long days, while the horizontal fly delivers fast, intuitive access with a clean, uninterrupted silhouette.
Made in Italy. Designed for life.
Every pair is produced by expert manufacturers in Northern Italy using sustainably sourced fabrics from Italy.
Soft enough for everyday wear. Technical enough for performance.
Built to outlast trends, workouts, and washing machines alike.
Where science meets comfort.
To improve men's health and
comfort from the base layer up.
