Classic Ck
Color: 3 Black
Size: Large
I got the classic ck boxers and they fit good. Sturdy waist band and regular rise are good features. I think these are great for work at the pizza shop as they are comfortable. The legs are a hair wide but since there sturdy 100% cotton they have some support. My problem is if I get boxer briefs they have a low rise. Overall I like them just nice and basic.

It gently cups your bottom
Color: 3 Black
Size: Medium
I purchased mine in March 2026 but the box looked really old like it’s old inventory and it was all bent up and opened. The content looked new so I didn’t return it. These boxers SHORTS are cut like their boxer BRIEFS in the rear and bottom so the boxer shorts tuck up against the rear end but still has loose leg holes so it’s still considered ‘shorts’. The way it’s cut, it almost feels like it ‘cups’ your stuff so if you wanted loose fitting shorts with lots of breathing room then you may want to look at other brands. I prefer a little more room under there myself. The knit cotton is soft and comfortable like their boxer briefs. The waistband is nice and sturdy with their brand logo. Mine also were sewn crooked so it’s a little goofy with poor quality control. Again it didn’t bother me enough to return it since they will throw them in the trash and fill up our landfill. I still gave it 5 stars because some people might like that gentle cupping style but it’s not for me.

Great Boxer shorts for a decent price.
Color: Black
Size: X-Large
This is my first try at this brand and style and I really like them so far. The material is soft but substantial (not sheer or flimsy). The piping, trim and stitching is quality made. I recently switched my rotation from mainly "boxer briefs" to more boxer style because I had tired of the tightness on my thighs. I bought 2 brands to try out the differences and I really wish I had just bought 2 packs of the Calvin Klein's. The leg length and width of the opening give great comfort and they look good doing it. About the only negative I could possibly raise is they still use a sewn tag, and oddly there is a fully sewn label and next to it is a partially sewn tag, so that one end is loose. I expected it to be an irritant, but so far I've not felt it, which is a relief. I would definitely buy this quality product again.

Fine quality but not the traditional CK slim fit
Color: Blue Bay, Minnow, Medieval Blue
Size: X-Large
I’ve been wearing Calvin Klein knit boxers on and off for 20 years. The boxers I’ve been wearing were short rise, slim fit, shorter leg - not quite a trunk, but close. And certainly not a boxer brief. They had a snap for a fly and were jersey knit so they stretched at the leg opening just enough not to ride up the leg. Admittedly, it has been several years since I last looked for (and bought) those boxers because they’ve been relegated to sleep wear only. The boxers you see here are the only knit non-boxer briefs I could find sold by Calvin Klein as of July 2024. They are about as different fit-wise from the boxers I just described above as anything I could imagine. And exceptionally far from the Calvin Klein ethos of a slimmer, sleeker, modern fit. These current boxers appear to be of fine quality, both material and construction. Beefy jersey cotton. But they have an exceptionally long rise (I’m 6 feet even) and are as loose as balloon pants. I have a hard time believing they carry the Calvin Klein label … they’d be more at home at Polo, Nautica, or Tommy Hilfiger. In fact, I would not be shocked if the CK boxers came out of the same factory with the same specs as one or more of those other brands. I will be keeping these boxers only because I bought them for the express purpose of sleeping in them and nothing more. I would be concerned about them properly fitting under even the loosest fitting pants I own. If that’s your jam, you should have no problem with these. But as someone attracted to the CK brand, I bet you’ll be disappointed with these as your daily undergarment based on the fit alone.

Not Just for Men — Great Sleep Shorts
Color: 3 Black
Size: Medium
I actually bought these for myself to wear as sleep shorts, and they’ve been great. The fabric is soft and breathable, and the waistband is comfortable without being tight. They hold up well in the wash and don’t lose their shape. If you like something loose and easy for lounging or sleeping, these are a great pick.

Lazy and cheap!
Color: Blue Bay, Minnow, Medieval Blue
Size: Medium
Picture: Behind the new size M (32-34 waist) CK boxers are an older pair of XL (40-42 waist) looney toons boxers and another new pair of Polo boxers, size L (36-38 waist). You will notice the Polo's are slightly longer (old boxers' waist band is folded down, out of the way, for visual). What is not obvious is the fact that all three pairs have almost identical width. And just like the Polo's, you can see the excessive amount of extra material sewn under the CK waist band. Apparently, some overpaid, undereducated, decision maker at CK still wears tube socks and thinks they're comfortable. Give us a break! We the consumers, the source of your paychecks, deserve better than tube socks and baggy diaper boxers. Making one size fits all boxers and simply changing the waist band to fit different sizes is lazy and cheap! And really shows how poorly CK's executives think of their customers. Polo, as you can see from the picture, is doing the same stupid, cheap, lazy, one-size fits all scheme with their boxers too. Oh yeah, last but not least, the CK boxers have no legs at the crotch, so they literally ride up the inside of your legs as soon as you put pants on. LAZY AND CHEAP IS ALL I CAN SAY!

Great undies for men.
Color: 3 Black
Size: Small
I really like these. They fit around my legs perfectly. Not too loose and not tight. They are comfortable and breathable and they've held up great over several washes. I ended up ordering more in a multi color pack. I highly recommend these.
