I was a bit skeptical about the price considering that they are name brand and the reviews about knock offs. I don't know enough about CK underwear to tell you if they're knock offs or the real deal. Im also not that concerned as I got what I paid $23 for and it was well worth it. I cut off the excessive amount of tags (and yes it comes with 3 pairs, the other 2 are in the wash) I have a size 28 waist, fairly endowed in the front, but no junk in the trunk. The fit is great, I wish this style came with a front fly, I know other CK briefs do, but I like that these are 95% cotton and 5% elastane, it gives it the right amount of stretch without sagging or hanging out one side by the end of the day. Im also happy that they don't dig into my legs. Im most happy with how my girlfriend likes the way they accentuate the family jewels and after 2 years, I finally have a pair of briefs that she loves when I put them on just as much as she loves to take them off. Hence, why the other 2 are in the laundry, I think for any  male thats definitely worth the buy right there.
