Product Insights
Le 31's Striped-Band Brief pairs TENCEL Modal with organic cotton for a silky, breathable feel that absorbs 50% more moisture than cotton and reduces friction to prevent chafing, while the double-layered front pouch offers moderate daily support and a smooth, modest look. Its low-rise cut hides under low-rise jeans, but the front pouch is ½″ narrower than competitors and overall fit runs a size small. The fabric stays soft after washing, resists pilling, and is sustainably sourced: 47% organic cotton (LCA-verified) and 47% TENCEL Modal (50% lower carbon/water), making this $19 brief a value in verified sustainable fibers.

Très confortable
Bon produit
À part, le fait qu'il soit manufacturé légèrement petit pour la taille, d'où la note 4 plutôt que 5, ce produit est de bonne qualité. Reste à savoir si ce produit sera durable; mon pronostic serait plutôt positif.
