Reviews

I’ve lost weight and wanted something more flattering underneath. Crossfly trunks are perfect! The fabric is thin but strong, feels soft, and the pouch gives a bit more room than normal.

Tech that matters

All our underwear feature our patent-pending X-Fly for quick access when nature calls and the internal support pouch, the Coccoon which eliminates skin on skin discomfort and chafing.

STYLES

• Pro 7" Boxers are best for those who require more breathable, sweat-wicking underwear.

• IKON / IKON X come in shorter lengths (3 and 6 inch) and are made from super soft modal fabric
