Product Insights

The Le 31 3" Contrast-Seam Trunk Organic Cotton offers a true-to-size fit that stays in place, with a short 3-inch inseam that exposes inner thighs—trading friction risk for cooling airflow. Contrast stitching and the short cut create a sporty look missing from longer, monochrome trunks, though the seam color may differ from photos. Cold-water washing and air drying prevent shrinkage, while tumble-drying can cause up to 10% shrinkage. At $19, it competes with 3-pack unit prices from Quince and Danish Endurance, and as a Simons-exclusive Canadian design, its contrast seams set it apart from DTC brands.
