Product Insights
The Le 31 3" Neutral-Hued Stretch Trunk blends TENCEL modal and organic cotton for a fabric that is 50% softer than standard cotton, wicks moisture 20% faster, and offers breathability. Its TENCEL modal is EU Ecolabel-certified, reducing carbon emissions by 50% and water use by 10–20 times compared to conventional cotton, while being biodegradable; the organic cotton is pesticide-free. The trunk resists pilling, low shrinkage (3–5%), and leg bagging, with shape retention through washing. However, buyers report the waistband feels uncomfortably tight, and the actual color is duller than product photos, indicating a tradeoff between comfort in the waist and aesthetic expectation. Air drying is recommended to preserve spandex recovery.

Compared within this brand.
| 3" Neutral-Hued Stretch Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy short trunk with a 3-inch inseam, made from 47% organic cotton, 47% TENCEL modal, and 6% spandex, in a fitted low-rise cut with a double-layered front, smooth no-logo exterior, and four neutral colorways from Small to X-Large. One customer review noted the elastic waistband may feel uncomfortably tight, and the actual color can appear duller than in product photos, so factor that in if either matters to you.[1,2] | 3" Colourful Stretch Jersey Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy trunk made of 47% organic cotton, 47% TENCEL™ modal, and 6% spandex, with a low-rise silhouette, a 3 inch inseam, and a wide white elastic waistband that sits below the navel. It suits shoppers who prefer a plain, single-color look, available in Green, Blue, and Red in sizes Small through Large, though the variant data lists X-Large only for the Red colorway.[3,4,5] | 2.5" Striped-Band Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy everyday trunk in an organic cotton and TENCEL modal blend: reviewers report all-day comfort at the office and relaxed lounging, with a stay-put wide waistband and a 2.5 inch inseam on a low-rise cut. It suits shoppers drawn to more sustainable materials, though some report noticeable shrinkage after washing and suggest sizing up, and the cotton blend can trap heat during high-intensity workouts while a few note durability may be a trade-off.[6,7] |
