Product Insights
Le 31's Stretch Wool Pant in London Fit combines a 7% wool blend with recycled polyester for natural odor resistance, thermoregulation, moisture wicking, and wrinkle recovery, while a subtle taper from knee to ankle avoids a boxy silhouette; however, maintaining shape requires air drying, a 24-hour rest between wears, and avoiding tumble drying, though the odor-resistant wool allows multiple wears between washes—a value proposition underscored by its $49.95 sale price, undercutting typical sustainable trousers priced $50-100 higher, and backed by Canadian design from Simons-exclusive Le 31, with free in-store hemming and a matching blazer available for a full suit.
Verified claims
- Fabric
- Wool and recycled-polyester stretch blend with natural odor resistance and thermoregulation.
- Fit
- Subtle taper from knee to ankle avoids the boxy silhouette of a straight cut.
- Thermoregulation

- Wrinkle recovery
- Polyester provides shape retention and wrinkle recovery for all-day crease.
- Care
- Air dry and 24h rest between wears preserve shape.
- Drying
- Air dry flat; tumble drying shrinks wool fibers.
- Rest period
- Pants need 24-hour rest between wears to recover shape.
- Wash frequency
- Odor-resistant wool allows multiple wears between washes.
- Value
- At $49.95, this price eliminates the typical $50–100 sustainability premium.
- Recycled content
- Fabric blends wool with recycled polyester from plastic bottles.
- Design pedigree
- Le 31 is a Simons-exclusive Canadian-designed brand; at $49.95 sale, its wool-blend trousers undercut DUER and Ballin's.
- Sustainability
- The stretch wool blend incorporates polyester made from recycled plastic bottles, an eco-feature typically found in $100–$150 trousers.
- Tailoring
- The pant has an unfinished 36-inch inseam and can be hemmed to any desired length, with complimentary in-store hemming available; the London fit sits between straight and slim for a precise tailored line.
- Matching suit
- A matching blazer (model 12016-217161) in the same stretch wool-recycled polyester fabric is available to build a full suit.
- Design origin
- These trousers are designed in Canada and sold as a Simons exclusive.
