I absolutely love the style, the feel and look of this underwear. However, at the end of the day, they lost their shape and the elastic on the legs openings looked stretched. The support was gone. I did order a smaller size (medium) to see if that would work better for me.

As a long time purchaser of Core Signature Low Rise Trunks I have been disappointed with the fit and fabric used for the trunks that I recently purchased from C-IN2. In short, they do not provide me with the support that I experienced with earlier produced trunks. Could it be that a different manufacturer and fabric is being used today, as contrasted with the product offered by C-IN2 around 5 years ago?

I've been wearing the 4023 Core Low Rise Trunk M exclusively for 20+ years, and was crushed when they were discontinued. So i was thrilled to discover that what looked like the exact same trunks were available again, albeit with a style number 100023, which i assumed to be a continuation of the 4023; they certainly look the same in the photos. I also have at least a dozen pairs to compare them to. Alas. The fit is not quite the same; they're a bit larger all around, and saggy and looser where they used to be perfectly snug. So, not as comfortable. Don't know where the difference lies: perhaps a slightly different fabric, or an adjusted cut? They're close, but not the same. So disappointed.

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!
