Comfortable and fashionable
12 October 2022meetchman

originally posted on calvinklein.com

I recently got these underwear as part of a wardrobe overhaul, and wow are they comfortable. They're form-fitting and supportable, but they stretch well with the body,. Additionally, they don't feel suffocating and are very breathable - this is absolutely key during hot Texas summers and falls. Importantly, they're also fashionable, and I somehow feel more confident wearing these than I do my older underwear. These were a great pickup!

Over the last several years I have noticed the quality & craftsmanship of CK products really going down. I have been loyal to CK when it comes to underwear fit, quality & product longevity.. heavy use & laundering then lasting at least 2 years minimum. The last couple of years I have bought 3 packs of this underwear & the microfiber version as well. I am lucky to get 6 months of wear before they start falling apart, losing shape.. that's w/ a gentle wash cycle, no drying. The biggest issue I am having is the seam on the leg band, I always feel like when I reach down for an adjustment there is a thread from somewhere wrapped around my finger. I am done paying a premium for that.It seems CK is more focused on catering to certain people and ideologies than providing ... MoreOver the last several years I have noticed the quality & craftsmanship of CK products really going down.

Great but with one flaw

Was very happy to see CK bring the Steel line of boxer briefs back as I have a few pairs of the originals and love them. The new material is great (although not as soft) true to size, and very comfortable. However I admit that these unfortunately do ride up your legs more than I'd like, more than any other CK boxer brief I own. I constantly find myself pulling them back down to reposition. Frankly, after washing and drying, I think the legs are a bit short for a boxer brief, which contributes to the constant ride up. They are no doubt comfortable, but this will likely keep me from buying more.

If you've got any self-respect, you pick these.
19 October 2022

As someone who has an X-taper build; big chest, narrow waist, big legs then you'll find so much underwear will eventually give you a wedgy, and get uncomfortable itchy, sweaty. All the nastyness. Well boxer briefs is the best of both worlds. These are so comfy and worth every penny, I simply cannot stand tight clothes which seems to be a trend. These pants taper nicely around my body as its stretchy and its not too tight. I'm a hip size of 35 or so, naval around 33'ish and these are super comfy around my 27 inch thighs. I know I'm being specific but if your like me, get these. Also I believe they use mother of pearl buttons rather then your standard cheap plastic buttons, so its a nice touch. I'm buying this solely from now on, they just do not creep into my butt.

Inconsistent sizing
22 December 2022

Calvin Klein trunks are the only underwear I buy and whilst sometimes they are perfect other times the sizing is slightly off and it is really annoying. Of the last 5 times I have purchased their cotton stretch trunks three of them were different lengths and width in the leg area. They were slightly shorter than normal making them uncomfortable. The description of the product however is always the same. So to Calvin Klein I say either get more consistent with the sizing of your product or provide better descriptions if they are designed to be slightly different.

Smooth & comforting!
19 September 2022

The Calvin Klein Micro Stretch Briefs are great because they are extremely smooth and comforting. I received them a few days ago and washed them before trying them on. They come with flexible stretch for maximum mobility, and the smooth microfiber material provides a comforting feel. Definitely quality you can expect from a known and reputable brand like Calvin Klein.Plus, the colors are amazing! I got these with 3 different shades of blue and they look amazing! Definitely recommend these and will buy them in the future as well!

Square cuts that poke at the bottom
8 December 2022

Disappointing. They are really square-cuts, not trunks. The cross-seam at the bottom of the front pouch pushes up and nags against me, and the front seam is also too short. They are also so low-rise that they feel unstable.I love the long-discontinued Elements NP1951O boxer briefs and NP1952O trunks, they were so well shaped with 7 panels; perfect anatomical fit.

Still the coolest, mass-produced mens underwear
3 September 2022

I’m giving these 4 stars at the moment because I’ve only just started wearing them. Bought same CK stretch trunks (different colours) in 2021 and they didn’t last very long at all. The inseam developed holes far too quickly due to the material being so thin. It was embarrassing wearing such holey CK’s for price I’d paid. Especially as I’ve worn this style for over 20 years now. Purchased the same CK stretch trunks (again, different colours) at the start of 2022 and the inseam material is much thicker. So far, so good. I’ll reserve judgment on the new set I’ve purchased just in case they’re the same as the 2021 set. But I do really dig the colourway! Hope they last…

Super Comfortable Briefs!
9 October 2021

After using these briefs, I’m extremely impressed! The first thing I love about these briefs is how well they fit. They perfectly matched the size I had ordered. The next thing I love about these briefs is how stretchy the elastic band is. The briefs effortlessly conform to my waist. This leads me to my next favorite feature about these briefs: their comfort. The waist band doesn’t leave any marks on me, unlike other brands I’ve used in the past. Additionally, the briefs themselves are made of extremely soft fabric. Another noteworthy feature I’d like to point out is how well the wicking absorbs sweat. I no longer have to worry about bad odors lingering throughout the day or sitting in sweat. These briefs have helped keep me fresh all day long. Finally, I really ... MoreAfter using these briefs, I’m extremely impressed! The first thing I love about these briefs is how well they fit.

Finally, I really appreciate how many shades of colors are included. It’s the perfect mix of dark and light shades. This is beneficial for when I’m wearing dark versus light bottoms and don’t want people to be able to see through. Overall, I’ve been very pleased with these briefs and would highly recommend them to anyone in search of a comfortable and reliable set of briefs that are sure to keep you feeling great!

Wow!!
22 September 2022

I absolutely love these. Perfect fit. Perfectly comfortable. They give me an abundance of confidence. CK knows how to make clothes, and their underwear are the highlight of their production. I used to buy Duluth and I really liked them, but they don't compare to these. I wish I could convey with words how perfect these are. I'm 6' 225lbs and I got the XL and they're perfect- i normally wear 36"-38" waist. Give these a try, i guarantee that you'll love them!!
