Low-rise cotton trunk with a clean, no-bulk leg finish.
The C-IN2 Core Low Rise Trunk delivers reliable everyday comfort in a compact, modern silhouette. Sitting lower on the waist with a shorter leg, it creates a streamlined profile that feels clean, easy, and familiar from the first wear.
Crafted from soft, breathable 100% cotton, it offers a natural feel with all-day comfort. A 2-ply contour pouch provides supportive structure and room where it matters most, while the refined leg finish reduces bulk for a smoother, more flexible fit. Finished with a shorter 2.5" inseam and signature waistband, it’s classic Core comfort—updated with a more modern edge.

- JSJon S.Verified BuyerReviewingCore Low Rise Trunk WhiteI do not recommend this productRated 1 out of 5 stars2 months agoIt seems that C-IN2 contracted
It seems that C-IN2 contracted with a different manufacturer to produce the Core Low Rice Trunks that I I recently purchased. I ordered a medium size and unfortunately the trunks are baggy and oversized compared to the trunks I had ordered in the past. They dont provide the same support that was available in the past. In short, if you ordered Core Low Rise Trunks in the past, you will be greatly disappointed ordering them now. The fit of these trunks is terrible.

Waist is mid-rise and the fabric runs up all the times. Seems the cut changed.
- JGJerry G.Verified BuyerReviewingCore Low Rise Trunk BlackI do not recommend this productRated 1 out of 5 stars2 months agoYou changed the ribbing around
You changed the ribbing around the leg. It does not hold up after using for the day as the old 1 inch thick ribbing did. Its tiny now and feminine looking and feeling. Please go back to the masculine thick ribbing that worked and held up after a days use. I want to wear mens underwear NOT feminine panties!
