Less bulk at the leg. Same trunk you trust.
The Core trunk, refined: a shorter 2.5" inseam and a smooth leg finish that lies flat on the thigh. Everything that made it a daily pick stays — the soft cotton, the supportive pouch, the square cut — minus the bulk at the opening.
Fabric
100% Cotton. Soft, breathable, and natural against the skin — comfort that holds up wash after wash.
Fit & Silhouette
Men's low-rise cotton trunk — sits below the natural waist with a shorter 2.5" inseam for a cleaner, more compact fit.
Contour Pouch
Sculpted 2-ply contour pouch with center-seam construction — extra room and supportive shape, no bulk.
Smooth Leg Finish
Refined low-bulk elastic lies flat on the thigh — no pinching, no ridge, invisible under slim pants.
Waistband
1.5" exposed elastic waistband with C-IN2 branding — the signature above the square cut.
Fit note
True to size. For a looser fit, go one size up.
Care
Machine wash.
Imported.
Core

I have purchased Cin2 underwear for years, I am a little disappointed with the grey Core briefs , as the leg stretches and becomes very loose after 2nd time wearing
I usually go with the black Cin2 briefs
