    • The Legends of the Loincloth - Calvin Klein's Magnum Opus
Size: Medium Color: 2 Blue Shadow Body W/Blue Shadow Waistba...
If the ancient Greeks were around today, they would have one simple word to describe these Calvin Klein Men's Cotton Classics 5-Pack Boxer Briefs: "Eureka!" These, my friends, are the pinnacle of human achievement, a testament to the progress of mankind, and the eighth wonder of the world (move over, pyramids). I'm in my mid-40s, and I can proudly proclaim that I've been rocking these bad boys for what feels like an eternity, and guess what? They're still standing strong, much like my devotion to pizza on Fridays. Ladies and gentlemen, allow me to introduce you to the Calvin Klein Boxer Briefs – the eighth wonder of the world, a true masterpiece in the realm of undergarments. Not only have I owned them all my life (well, at least since I discovered boxers weren't just tiny pugilists), but these babies have been a constant source of comfort and confidence. If I could, I'd have these boxer briefs framed on my wall, right next to my framed poster of Einstein sticking his tongue out. Now, let's talk about their magnetic appeal. You see, these boxers aren't just a piece of fabric; they're a commitment to excellence. They've got that magical blend of cotton that feels like a gentle hug from an old friend, and they provide support that makes you feel like you could conquer the world (or at least conquer the office on a Monday morning). And speaking of conquering, let's talk about the ladies. These boxers have a magical effect on them. It's like they emit a secret pheromone that says, "I'm smart, stylish, and ready for anything." Maybe it's the classic Calvin Klein waistband that exudes sophistication, or perhaps it's just the aura of sheer awesomeness these boxers bestow upon you. Whatever it is, be prepared for some admiring glances and compliments. Just make sure to keep your ego in check; we don't want to start a cult (or do we?). Now, here's the kicker: a million companies are trying to reproduce what is already a fantastic undergarment. It's like trying to recreate the Mona Lisa with crayons. Calvin Klein has set the bar so high that aspiring contenders should just bow down in homage. In conclusion, these Calvin Klein Men's Cotton Classics 5-Pack Boxer Briefs aren't just underwear; they're an ode to the triumph of human ingenuity. They're the sartorial equivalent of discovering fire or inventing the wheel. So, if you want to feel like a modern-day Hercules, give these boxer briefs a try. They're not just underwear; they're an investment in your own legendary status. Bow to the boxers, my friends, bow to the boxers! ... show more

    • Like a Rolex, it’s a classic and a smart choice
Size: Medium Color: 2 Blue Shadow Body W/Blue Shadow Waistba...
There’s a reason why it’s called the classic, bc it simply works and lasts. They continue to make refinements over the years, and the 100% cotton material has gotten slightly thinner to improve breathability without sacrificing the durability or go out of shape like the other materials. They have gone to a tag less design, which improves comfort. The only knock I have with this latest version is they have shorten the legs a bit, which make them ride up and noticeable if you stand up and sit down frequently or exercise vigorously. ... show more

This is the best underwear ever! Looks great, feels great... It's Calvin Klein, so that's what you'd expect. The fit on them is amazing. One of the most embarrassing things that can happen to a man is to have his pants pulled off during a fight. If that happened while I was wearing this underwear, I would just confidently blow kisses to any bystanders. ... show more

    • pretty nice though the fabric isn't soft
Size: Large Color: 2 Blue Shadow Body W/Blue Shadow Waistba...
Good fit and comfort. Some pilling on the inside after 15-20 wash cycles, but they still look good and hold their shape. The fabric is a bit rough to the touch, but not uncomfortable to wear. Quite breathable. These are the closest to the fit of the old CK microfiber trunks I could find, although the fabric is very different of course. This classic cut is my favorite-- not excessively tight boxer-briefs, not the "biker short" versions that go nearly to your knees. Something in between, but not loose like woven boxers. I'd think this would be popular, but it turned out to be hard to find. The microfiber version I loved doesn't seem to exist now, since CK seems to drop products every couple of years. Rebranding constantly might seem smart to their marketing folks but practically it makes it unnecessarily complicated to restock a favorite. I ended up having to try a half-dozen variants to find 2 that were similar to what I was still buying 2-4 years prior. Inefficient, and wasteful-- since the other 4 variants were returns. Good fit, good durability, looks nice, needs no special care. Recommended. ... show more

I recently purchased the Calvin Klein Men's Cotton Boxer Briefs, and I couldn't be happier with my choice! The fit is perfect, providing just the right amount of support without feeling restrictive. The cotton material is incredibly soft and breathable, making them ideal for all-day wear. I've worn these for both casual and active days, and they hold up wonderfully in both situations. The colors and design are stylish yet classic, adding a touch of flair to my wardrobe. Plus, they wash well without losing their shape or comfort. ... show more

    • Sexy ahh briefs
These are my favorite briefs. I usually wear 31x32 pants, mostly medium shorts. Large of these were too big. Medium is good, smalls also fit though but feel a little tight.
