This smooth and stretchy boxer brief from Calvin Klein’s premium collection has a silky luxe feel and provides a classic yet very flattering look.

Also, thanks to their lightweight feel and comfortable contoured pouch these are great for both everyday wear and special occasions.
Bottom Line: A premium underwear option at a reasonable price—you’ll love the silky feel and the stretchy fit that offers a flattering appearance.
Here’s everything included in this guide:
Who Should Buy
We tried the Calvin Klein Black Micro Boxer Briefs and put them through our daily routine with a mix of work, activity, lounge, and rest scenarios. As a result, we found them to be a great choice for:
Premium underwear fans looking for a luxurious feel and stylish appearance.
Boxer brief enthusiasts that prefer smooth and stretchy fabric blends in a simple monochromatic design.
Those in search of a traditional boxer brief silhouette that provides an untraditionally much more flattering fit.
Professionals and those with public-facing roles looking for a clean and polished appearance that forgoes leg hems or any bulkiness from their base layer.

Who Should NOT Buy
After testing the Calvin Klein Black Micro Boxer Briefs in a variety of everyday situations, we think it’s probably not the best underwear option for certain occasions and uses.
In particular, while these boxer briefs are more than comfortable enough for everyday wear, they’re less suited for the extra comfy and roomier feel that’s often preferred for lounge, rest, and sleep.
In that case, we recommend the Calvin Klein Cotton Stretch Boxer Briefs, which are well-suited for both everyday wear and maximizing your rest and relaxation with an extra soft fit.
Another occasion in which these might not work the greatest is during workouts, physical activity, or any situation where you would prefer a high level of support from your underwear.
We found that the waistband offered plenty of support and that the stretchy fabric blend allowed a full range of motion, but the contour pouch is certainly more tailored to everyday wear and not ideal for high-impact activity.
From testing other men’s underwear brands during workouts and physical activity, we would recommend a boxer brief like the Tommy John 360 Sport.
These workout boxer briefs have a luxe feel and are specifically designed to handle physical activity.
Fabric & Design
The Calvin Klein Black Micro Boxer Briefs use a smooth and stretchy luxury microfiber fabric with blend of 75% reprocessed nylon and 25% elastane.
You’ll easily notice the high degree of stretch and recovery that this blend provides, as these boxer briefs comfortably move with your body without shifting around, riding up, or constricting in any way.

We love how this fabric blend has a silky feel to it and the slight shimmer in its appearance provides a flattering and stylish look.
We’re also impressed by the one-piece seam-free back design that provides a sleek look and smooth feel against your skin.

These have a lightweight design with a low profile that still manages to provide support where it’s needed.
These boxer briefs are available in several classic color options.
The care instructions for these boxer briefs are machine wash.
Waistband
The waistband for these boxer briefs has a smooth and secure elastic design composed of 74% polyester, 13% polyamide, and 13% elastane.
We like the medium rise waist on these boxer briefs that both provides plenty of coverage and maintains an elevated look.

Additionally, on the outside of the waistband you’ll notice the brand name on the center-front in classic Calvin Klein font with a downplayed styling.
Overall, we found that this waistband does a great job of staying put (no sliding or shifting around) while remaining non-constricting and comfortable enough for extended wear.
Pouch
The Calvin Klein Black Micro Boxer Briefs have a classic contoured pouch that is double layered for a comfortable and supportive fit.
We found that by pairing the sleek microfiber fabric with the contoured pouch design, these boxer briefs provide a flattering and classy look.

While a classic contour pouch typically does not provide targeted support to the groin, we feel that the stretchy fabric blend of these boxer briefs adds to overall pouch support, making it more than suitable for everyday wear.
Additionally, note that a classic contoured pouch design is not particularly roomy when compared to pouch-specific boxer brief designs, but the stretchy nature of this fabric does provide a good amount of give.
Legs
The smooth no-bulk fit of these boxer briefs is in part achieved thanks to their raw cut leg design.
The raw cut forgoes a hem and any need for seams (which are the primary cause of underwear lines on the outer layer), providing a very clean, no-fuss look.

While a raw cut leg is untraditional in men’s underwear, we’ve found that the feel is largely unnoticeable from traditional leg options and in some cases can even be more comfortable.
We noticed that the raw cut leg design paired with the stretchy nature of the fabric creates a very smooth and irritation free layering experience that drastically cuts down the need to adjust throughout the day.

The inseam length of these boxer briefs is a standard 5 inches.
Note that the Calvin Klein Black Micro product line also comes in a shorter leg length trunk option.
