Calvin Klein Microfiber Stretch Boxer Brief 3-Pack in Blue Multi — Size Medium

Calvin Klein is the definitive American premium basics brand — a label whose underwear line has been one of the most recognized and broadly trusted in the market for decades, built on clean design, quality construction, and the signature waistband that has become one of the most recognizable brand marks in the category. The Microfiber Stretch Boxer Brief 3-Pack delivers the Calvin Klein quality standard in a silky-smooth Polyester microfiber construction with a meaningful Elastane content that provides exceptional stretch and second-skin fit across the Blue Multi colorway set. Brand new with tags. Package was potentially opened and repackaged for photos and measurements — will ship in original packaging. Note: sizing on box does not necessarily represent the size being purchased — please rely on the size listed here and the measurements below.

The 92% Polyester, 8% Elastane construction is a performance-forward specification for a premium microfiber boxer brief. High-denier Polyester at microfiber fineness produces a surface that is smooth, lightweight, and virtually frictionless against the skin — a wearing character that sits against the body without friction or bulk and disappears under clothing in a way that a standard knit Cotton brief cannot achieve. The 8% Elastane content provides the stretch and recovery that gives the boxer brief its characteristic second-skin fit — moving with the body through the full range of daily activity and returning to its original shape consistently, keeping the fit secure and comfortable without the waistband rolling or the leg openings binding. The signature Calvin Klein waistband is the brand mark that signals the construction standard and that buyers across decades have recognized as the quality indicator in the premium underwear market. The Blue Multi colorway set provides tonal variety across the three-pack that suits the everyday rotation well. Style #NP2769X.
