Everyday wear as a soft, form-fitting trunk

Product comparison
Compared within this brand.
| 2.5" Organic Cotton Trunk: Choose this for a very short trunk style: it has a 6.5 cm (2.5 inch) inseam that sits low on the thigh, a form-fitting silhouette with a contoured front pouch, and a wide elastic waistband in bright blue with white script branding. It suits shoppers who want soft stretch organic cotton (95% organic cotton, 5% spandex) in a smooth, matte knit, double layered at the front, with sizes small to x-large and color options including Black, Patterned Black, and Patterned Blue. Note the care requirements: wash inside out at a maximum of 30 degrees Celsius with dark colors washed separately, and no bleach or tumble drying — instead reshape gently and line dry in the shade.[1,2,3,4] | 2" Powder-Blue Trunk Organic Cotton: Choose this for a low-rise, short-cut trunk with a 2-inch inseam and a contoured front pouch that is double layered. Its stretch organic cotton jersey (95% organic cotton, 5% elastane) is described as ultra comfortable, with an elastic waistband printed with the brand's script text, and it comes in sizes from small to X-large. One wearer found it pretty soft but noted it was not as soft as some of their micro modal pairs, so prefer a different fabric if maximum softness is the priority.[5,6,7] | 3" Navy Stretch Trunk Organic Cotton: Choose this if you want a form-fitting trunk in a soft, stretchy organic cotton blend (95% organic cotton, 5% spandex) with a short 3-inch inseam and a low-rise elastic waistband that sits at the natural waist. It suits shoppers who prefer a smooth, matte fabric with a contoured front pouch and a solid navy look accented by a small white script logo. One wearer found it pretty soft but not as soft as some micro modal pairs they own, so ultra-soft fabric seekers may want to weigh that.[8,9,10,11] |
