Calvin Klein Cotton Stretch Classic Fit Boxer Briefs offer premium comfort and modern styling with a signature minimalist aesthetic. Crafted from soft, breathable cotton stretch fabric (typically 95% cotton, 5% elastane), these briefs provide all-day flexibility, shape retention, and moisture-wicking performance. The iconic elastic waistband features repeating 'Calvin Klein' branding in contrasting white lettering—subtle yet unmistakable. Designed with a contoured pouch, flatlock seams to prevent chafing, and a mid-rise fit, they deliver support without constriction. Ideal for daily wear, travel, or layering under slim-fit trousers. The 3-pack includes essential neutral tones: Black, Light Gray, and Navy Blue—versatile for any wardrobe. Packaged in Calvin Klein’s signature clean retail box featuring a model shot and 'Cotton Stretch' labeling, confirming authenticity as a department store genuine item (as indicated by '专柜正品'). Perfect for men seeking understated luxury, durability, and timeless design in foundational underwear.
