The answer is easy — it has a great fit and , an iconic simplicity, and a modern hip image! There is nothing really quite like Calvin Klein undergarments. It popularized the boxer brief, updated the traditional brief, and gave boxers a more comfortable fit. And oh, that waistband with the Calvin Klein name emblazoned on it needs to be thrown into the mix as well. Who hasn't seen that name popping out above many a pant waistline?

CK hit the market offering men a new twist on the tightie-whitie underwear. Calvin Klein men’s underwear from the beginning had a unique advertising campaign featuring celebrities, super-models, and fresh new faces to represent the brand. Now made by the Warnaco Company, this advertising approach of Calvin Klein briefs (and more) hasn't wavered.

Calvin Klein goes beyond just new underwear designs. They used new fabrics such as microfiber and gave the low-rise fit in underwear acceptability. And it didn't hurt that Brooke Shields, Mark Wahlberg, Kellan Lutz, Zoe Saldana, and Kate Bosworth were splashed across billboard ads in huge black and white photos displaying their underwear.

Celebrities aren't the only ones who love Calvin Klein underwear. Their microfiber briefs and boxer briefs also get high marks from customers for their construction and fit. Waistbands hold their shape with no rolling. Legs stay put and don't ride up. And the smooth-fitting fabric works under everything. Men also appreciate the silky, lightweight feel. 

T-shirts in all styles quickly became customer favorites. They are cut long enough to stay tucked in. The high-quality fabrics, with just a little bit of stretch, feel soft against the skin and provide a lean, put-together silhouette.

The Calvin Klein men's underwear line also includes long sleeping and lounging pants, cold weather long johns, hosiery in lots of styles, and woven pajama pants. Along with the underwear collections, this makes Calvin Klein briefs the go-to brand for men looking for comfort, style, basic and trendy colors, versatile cuts, and enduring quality.

Calvin Klein has become the world's first and finest designer underwear for men and now for women. Established in 1982, Calvin Klein made basic underwear something to be desired instead of needed. The sexiness and desirability of the products were really a turning point in the underwear marketplace. People were actually looking to buy underwear rather than just having Mom go out and buy some because the old ones were looking so bad. Underwear drawers definitely received a boost.

But don't think Calvin Klein Underwear was just a fad. Far from it. Quality, fit, and fabrication of the underwear design give it a long shelf or should we say drawer life. 

The CK line includes men's pouch underwear, briefs, boxer briefs, trunks, briefs, button-fly boxer briefs, and thongs. T-shirts include crew, muscle, long sleeve, and short sleeve t-shirts, and v-necks. Materials include microfiber, 100% cotton, cotton stretch microfiber pique, and traditional woven fabrics.

Briefs are slightly shorter as they only provide coverage up to the inguinal area. Trunks, meanwhile, cover more of the upper legs. Briefs fit snugger and as such offer more support compared to trunks

No, they fit true to size so you can order your regular size. For best results, please refer to our sizing chart before purchasing.

We recommend replacing your undergarments every 6–12 months. Do note that you may have to buy a new pair sooner if yours has holes, stains, and/or stretched-out fabric.
