Modern cut. Classic comfort.

Trunks are for guys who want boxer-brief security without fabric halfway down the leg. Core's version: soft 100% cotton, a compact 3" inseam, and a clean square cut that never bunches under slim pants.


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 3" inseam for a compact, streamlined fit.

Contour Pouch
Sculpted 2-ply contour pouch with center-seam construction — extra room and supportive shape, no bulk.

Leg Openings
Covered elastic leg openings sit flat at the upper thigh — no riding, no bunching.

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.

Reviews Summary
Customers say these trunks are comfortable and soft with good quality cotton material. Many praise the fit and support, though some note sizing inconsistencies. Several reviews mention they run small, with recommendations to order a size up. Common feedback includes appreciation for the low-rise design and snug fit, though some find the waistband loose or the leg bands not snug enough. A few customers report changes in manufacturing affecting fit compared to previous purchases. While most find them perfect for daily wear, some mention the crotch area feels restrictive or the low-rise sits very low on the hips.

    Another great pair of undies! C-in2 never lets me down

    I normally wear the low rise briefs in L. Butt, my boyfriend is after me to try new things and I thought this would be a good change that isn't too big of a change. As always C-in2 feel great and the fit in all the right places and keep thing where the need to be. I honestly can't keep them on long because now the BF is always trying to take them off!

    A very successful purchase

    They are very comfortable and fit very well. They are certainly designed for everyday life.
