Product Insights
The Le 31 Stretch Responsible Wool Suit Jacket in Stockholm Fit - Slim offers a tailored silhouette akin to Suitsupply's Milano/Havana fits, featuring mechanical stretch from weave geometry for 10–18% elongation and a crisp wool hand. Its recycled plastic bottle lining saves 59% energy and 71% CO₂ while resisting wrinkling, shrinking, and stretching, lasting 8–15 years. The jacket retains shape after wear and dry cleaning, and its breathable shell and moisture-wicking lining maintain a dry microclimate. Priced at $350 CAD, it undercuts comparable options like Tiger of Sweden's Justin and its own $395 variant at a $250 sale price, delivering European-milled responsible wool and full recycled-polyester lining surpassing competitors.
