Technical Specifications


Each pair of KOY GEAR underwear is carefully made with technical silver fibre fabric engineered by coating polyamide fibres with pure ionized silver. Silver's antibacterial effects have been put to use for centuries and are still utilized today for water disinfection, surgical masks, wound dressings, and in the engineering of spacesuits. When the coated fibres come into contact with moisture, the silver ions are released, effectively killing 99% of bacteria and preventing unwanted odours.

Temperature regulation

Our underwear regulates temperature using the heat conducting nature of silver and strategically placed mesh panels for optimal airflow and breathability. Premium modal fibre offers the perfect balance of breathability and comfort. Even on the hottest of days, our KOY GEAR underwear will provide supreme comfort.


KOY underwear features flat-lock stitching for a natural and comfortable fit, premium modal for an extremely soft and smooth feel, and 3D cutting to prevent underwear from riding up the thighs. Quality hand-picked modal fibre made from reconstituted cellulose guarantees a truly soft, smooth, and air permeable underwear that is resistant to both shrinkage and fading.
