Product comparison
Compared within this brand.
| 3" Tropical Flower Trunk: Choose this if you want a short, form-fitting trunk with a 7.5 cm (3 inch) inseam, a contoured front pouch, and double-layered front construction. It is made of stretch organic cotton jersey (95% organic cotton, 5% spandex) that the retailer describes as ultra-comfortable, with an elastic waistband about one inch tall featuring a tropical floral print and repeated Jack & Jones branding. It comes in sizes small through extra-large in three colorways: Navy/Midnight Blue, Patterned Blue, and Patterned Red.[1,2,3] | 3" Comfort Trunk Cotton: Choose this if you want a comfortable, close-fitting trunk in stretch cotton jersey (95% cotton, 5% spandex) with a 3-inch inseam, a contoured double-layered front pouch, and an elastic branded waistband that sits at the natural waistline. Its snug, mid-thigh cut and all-over skull-and-floral print on a medium blue background make it a bold, patterned pick rather than a plain basic. The saved listing shows SMALL-size variants in Navy/Midnight Blue and Patterned Blue, though this may not reflect all options the retailer offers.[4,5,6] | 3" Solid Comfort Trunk Cotton: Choose this if you want a short, comfort-focused trunk: it is a very comfortable stretch cotton jersey (95% cotton, 5% elastane) with a 3-inch inseam, an elastic waistband with a subtle embossed Jack & Jones wordmark, and a double-layered front. It comes in sizes small through X-large, and sits low-rise to just below the natural waist on the model shown. Note that the comfort description comes from the retailer listing rather than verified customer feedback.[7,8,9] |
