Product Insights
Le 31's Ash-Grey Soft Jean in London Fit is a slim-straight jean with a regular rise, crafted from a lyocell blend that ensures exceptional softness, breathability, and a tailored drape with minimal stacking. Its 10 oz stretch denim resists permanent bagging better than spandex-heavy options, though shape may relax and is restored by cold washing and hang drying. With an EIM score of 22, it offers a verified low-impact finish, but at $125 CAD it costs $65–$66 more than competitors. The main tradeoff is paying a premium for third-party verified sustainability and family-owned heritage over cheaper, self-reported alternatives.
Verified claims
- Softness
- Lyocell's smooth fibers eliminate the scratchy feel of cotton, so the jeans are soft from the first wear.
- Drape
- The lyocell blend gives these jeans a clean, tailored drape with minimal fabric stacking.
- Breathability
- Lyocell's porous fibers keep the jeans cool and dry by improving air circulation.
- EIM score
- Jeanologia EIM score 22 places these jeans in the low-impact band (0–33) on the 0–100 EIM scale, covering water, energy, chemicals, and worker health.
- Sustainability
- Le 31 publishes a concrete Jeanologia EIM score of 22 verified by a third-party finishing technology firm, and Simons' family-owned ownership makes eco-conscious material and finish choices more likely to survive cost reviews.
- Price comparison
- At $125 CAD, it costs $65–$66 more than competitors but includes verified low-impact finish.
- Fit
- Slim-straight fit like Levi's 513 with a regular rise at the natural waist.
- Care
- Order true to size; lightweight denim can relax at knees – cold wash and hang dry restores shape.
- Stretch recovery
- The 10 oz stretch denim resists permanent bagging better than spandex-heavy denim; shape may relax but is restored by washing and air drying.
- Shape retention
- Washing and air drying restores shape and minimizes knee sag.
- Heritage
- London fit refined over 60 years for Canadian customers: slim straight with regular rise.
- Organic cotton blend
- The denim blend includes organic cotton as part of its eco-conscious material mix.
- Design origin
- Le 31 jeans are designed in Canada, anchored to Simons' Quebec City headquarters.
- Washing instructions
- Machine wash cold with like colors and tumble dry low or hang dry; avoid bleach and wash every 8–10 wears to preserve the soft feel.
