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.

    It 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.

    You 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!
