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

- CJCharles J.Verified BuyerReviewingCore Low Rise Trunk Black (Smooth Leg Finish)I do not recommend this productBody Type ShortHeight 5' 10-6' 0Normal Size Worn LSize in Other Brands LSize Bought LRated 1 out of 5 stars4 days agoUpdated version is TERRIBLE quality!
My husband and I have more than 20 pairs of the old version of these and they’re great. This new “smooth leg finish” redesign is garbage! The waistband fits well, but halfway through the day, what should be tight fitting trunks have turned into boxer shorts. They stretch out so bad, I’m constantly trying to rearrange my junk. It’s a shame they discontinued my favourite underwear and replaced it with something so inferior.
Also, I’m being forced to choose a “body type” with my review. Where is average? Not 1 of your 6 options suits an average person. I’m 5’10” & 175

Leg bands become super loose and baggy after wearing for one hour. I’m a very lean person wearing a Medium.

After first wearing, leg openings are dramatically loose and baggy. So junk is just bouncing around and almost hanging out. I'm 6'2" 165lbs, so no reason for them to get stretched out on me. When initially tried on, they were comfortable and seemed to have potential. Maybe cheap materials and never tested?

Looses its shape very soon. Lower bands area around the thighs are made too thin, it cuts through skin and is irritatting.
