| 2.5" Microfibre Trunk: Choose this if you want a soft, stretchy microfibre trunk with a very short cut — it has a 6.5 cm (2.5 inch) inseam, a fitted low-rise silhouette ending on the upper thighs, and finished stitched leg hems. Its wide elastic waistband with large CALVIN KLEIN lettering front and back, contoured double-layered front pouch, and body of 88% reprocessed polyester with 12% elastane suit shoppers who like visible-branding, recycled-fabric basics. It comes in Black, Mint/Pistachio Green, and Red across sizes Small to X-Large.[1,2,3] | 3" Colourful Trunk Cotton: Choose this if you want a low-rise Calvin Klein trunk in soft, stretch cotton jersey (95% cotton, 5% spandex) with a short 3-inch inseam, contoured front pouch, and a contrasting elastic waistband. It suits shoppers who prefer minimal, no-pattern styling with subtle tonal branding, available in Golden Yellow and Green. Note that the listing only shows a MEDIUM size, so it may not fit if you need another size.[4,5,6] | 3" Colourful Ultra-Soft Trunk Modal: Choose this if you want a short 3-inch inseam trunk in a soft stretch modal blend (95% modal, 5% elastane) with a contoured front pouch, elastic logo waistband, and a colorful Dusky Pink look. Note that one long-term owner found the waistband less than very comfortable, so comfort expectations on the band may vary.[7,8,9] |
