Product Insights
Le 31's 2" microfibre trunk, made from 85% recycled polyester, offers an invisible fit under slim trousers with a two-inch inseam that eliminates thigh bunching, stretch fabric that prevents ride-up and forgives sizing, and a flat double-layer front panel that provides gentle support without showing through. It resists pilling, shrinkage, and warping after machine drying, dries quickly for sink-wash reuse, and packs flat—all for $20 CAD without the typical green premium. The primary tradeoff is reduced breathability in hot, humid conditions compared to cotton.

Very comfortable and well made
beau tissu
j'aimerais plus les boxeurs que j'achetais chez Simon's en microfibre le 31 de teintes fluo . ceux-ci sont se qui se rapproche le plus de votre ancienne marchandise . les teintes sont un peu fades et l'élastique reste à expérimenter sa durée
