Flex Trunk Black

The trunk that stays cool.

Square cut, short leg, full airflow. The Flex Trunk takes the most wearable silhouette in underwear and knits it in breathable cotton-modal mesh — a compact 3" inseam that stays cool and never bunches.

Fabric
57% Cotton, 38% Modal, 5% Elastane. Airy mesh knit with 4-way stretch — modal makes it softer than plain cotton, and the mesh keeps air moving against the skin.

Fit & Silhouette
Men's mid-rise mesh trunk — sits at the natural waistline with a 3" inseam for compact, balanced coverage.

Contour Pouch
2-ply contour pouch — sculpted support with natural lift.

Leg Bands
Smooth microfiber leg bands sit flat against the thigh — no ride-up, no bunching.

Waistband
1.5" elastic waistband with C-IN2 branding — soft hold, clean finish.

Fit note
True to size. For a looser fit, go one size up.

Care
Machine wash.
Imported.

Flex

Everyday basics in an airy cotton-modal mesh with 4-way stretch — softer than plain cotton, cooler than anything else in the drawer. Light layers for warm days and long ones.
