Product Insights
Le 31's 3-inch ribbed stretch trunk uses recycled polyester and reprocessed cotton to deliver a modern, low-rise silhouette that minimizes lines under slim trousers while reducing energy use by 50%. The ribbed jersey offers consistent sizing, resists pilling and shrinkage, and feels smoother and stretchier than cotton, but its moisture-wicking fabric trades some breathability in heat.
Verified claims
- Fit reliability
- The recycled polyester blend reduces overall shrinkage, while the ribbed structure helps the trunks hold their shape and elasticity after washing.
- Silhouette
- The 3-inch inseam and low-rise waist create a modern look with minimal lines under slim pants.
- Fabric feel
- Smoother and stretchier than cotton, with moisture wicking but less breathability in heat.
- Breathability
- Polyester is inherently less breathable than cotton, so airflow is slightly reduced, though the ribbed stretch jersey helps mitigate the difference.
- Shrinkage
- Recycled polyester blend reduces shrinkage; cold wash and low dry recommended.
- Durability
- Ribbed stretch jersey resists pilling and holds shape with minimal shrinkage.
- Brand heritage
- Le 31 is the exclusive in-house brand of Simons, a retailer founded in 1840.
- Material
- Recycled polyester and reprocessed cotton blend saves up to 50% energy and resists pilling and shrinkage.
- Styling
- The 3-inch inseam and squared-off silhouette avoid visible lines under slim trousers and project a modern, fashion-forward look.
- Environmental impact
- The recycled polyester is produced from post-consumer PET bottles and requires up to 50% less energy than virgin polyester manufacturing.
- Design origin
- Le 31 is designed in Canada.

Compared within this brand.
| 3" Ribbed Stretch Trunk Organic Cotton And Recycled Polyester: Choose this if you want a low-rise, fitted trunk with a short 3-inch (7.5 cm) inseam, a fly, and a narrow elastic waistband that sits at the hips below the natural waistline. Its fine vertical rib-knit stretch jersey is made of 65% polyester from recycled plastic bottles and 35% reprocessed cotton, with narrow turned leg hems that sit flat against the upper thighs on the photographed model. It comes in sizes Small to X-Large and four colors (Black, Grey, White, Baby Blue).[1,2,3] | 3" Neutral-Hued Stretch Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy low-rise trunk with a short 3-inch inseam, made from a 47% organic cotton, 47% TENCEL modal and 6% spandex blend with a smooth, matte-finish knit and no visible exterior logo. It comes in four neutral colors (Purple Grey, Ivory/Cream Beige, Hazelnut, Mossy Green) in sizes small through x-large, with a double-layered front and narrow stitched leg hems. Note that one reviewer found the elastic waistband may be uncomfortably tight, and one reported the actual color looks duller than in the product photos.[4,5] | 3" Contrast-Seam Trunk Organic Cotton: Choose this if you want a low-rise, 3-inch organic cotton trunk with a true-to-size, snug fit that reviewers say stays put through a full night's sleep, or for a polished look under shorts thanks to the contrast light-blue stitching and elastic waistband trim. Many reviewers find the fabric soft and comfortable for all-day wear, and most report it holds up well to wear and washing, though one found the material average in softness and occasional complaints cite medium build quality. If an exact shade matters, note that some reviewers say product photos can misrepresent the colors, so rely on the written description.[6,7] |
