Product comparison
Compared within this brand.
| 3" Blue-Patterned Trunk: Choose this if you want a short, low-rise trunk with a 7.5 cm (3 inch) inseam, made from 95% organic cotton and 5% spandex stretch jersey that the retailer describes as ultra-comfortable, with an elastic waistband with brand text and a double-layered front. It suits shoppers who like a navy base with an all-over small light-blue dot pattern, in sizes small through x-large. If you prefer plain fabric or longer leg coverage, the printed pattern and short inseam are worth noting.[1,3,4] | 3" Comfort Trunk Cotton: Choose this Jack & Jones trunk if you want a comfortable, close-fitting mid-rise style with a 3-inch inseam, made of 95% cotton and 5% spandex stretch cotton jersey with a double-layered front, contoured front pouch, and an elastic waistband bearing the brand's logo. Its all-over skull-and-floral print on a medium blue background makes it a statement pick rather than a plain basic. Note that the saved listing shows only size SMALL in Navy/Midnight Blue or Patterned Blue, which matters if you need another size.[5,6,7] | 3" Solid Comfort Trunk Cotton: Choose this if you want a 3-inch inseam trunk in very comfortable stretch cotton jersey, with a composition of 95% cotton and 5% elastane. It has an elastic waistband bearing the JACK & JONES wordmark, a double-layered front with a shallow contoured pouch, and a low-rise cut. It comes in sizes from SMALL to X-LARGE, though the rise described on the model reflects the analyst's reading of how the trunks sit rather than a stated specification.[8,9,10] |
