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.
