Stretch Responsible Wool Suit Jacket Stockholm Fit - Slim
This is a slim-fit ('Stockholm') single-breasted suit jacket for men, crafted in Canada from a European blend of responsible wool and recycled polyester with a satiny recycled-polyester lining. It features notch lapels, a welt chest pocket, two flap hip pockets, side vents, and a two-button front closure, designed to pair with the matching trousers (item 12016-229618). The light-gray woven fabric has a subtle micro-texture, and the jacket includes a center back vent for ease of movement.

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.

Deep Research
Price and value against comparable slim wool jackets
- The shell is cut from a European-milled responsible wool blend, a provenance detail typically found on jackets above $500 — its inclusion here at $250–$350 signals Le 31 prioritized fabric origin over margin, a key differentiator in the sub-$400 slim-wool segment.
- Within the Le 31 Stockholm-fit family, this responsible wool jacket at $350 regular price is the financial entry point: the identical silhouette in a Marzotto wool weave costs $395, and a similar slim-cut in a recycled-polyester suit runs $375, so this variant is the lowest-cost ticket to the brand's tailored recycled-wool system.
- Both the outer shell and the full satiny lining are made from recycled plastic bottles, so the sustainability story runs continuously through the jacket — in contrast to many wool-blend jackets at this price that limit recycled content to the face fabric and use conventional linings.
- Le 31 is Simons' in-house label designed in Canada, so the Stockholm fit is calibrated for North American sizing while leveraging European-milled responsible wool — a hybrid value that sidesteps the fit-compromise often encountered with imported European slim cuts.
- At $250 on sale, the Stockholm jacket goes head-to-head with Tiger of Sweden's Justin at $265, yet it replaces the Justin's half-lining and patch pockets with a full satiny recycled-polyester lining and side vents — delivering a more finished interior at an identical price tier.
How the jacket stretches without elastane
- Without an internal elastic fiber to fatigue, the jacket resists the bagged-out look that elastane-blend suits can develop at the elbows and back, returning more reliably to its original silhouette after each wear.
- Mechanical stretch wovens typically deliver 10–18% elongation — moderate compared to elastane blends — which is enough for the dynamic movements of a tailored jacket (reaching, bending) without introducing excessive flex that could distort the garment’s lines over time.
- Because the stretch is structural — housed in the yarn geometry rather than a vulnerable synthetic fiber — it withstands the heat and solvents of professional dry cleaning far better than elastane, so the jacket’s mobility and shape recoverability won’t degrade over multiple cleaning cycles.
- Mechanical stretch, built on a wool-polyester base, typically breathes better and maintains a natural woven hand feel compared to elastane blends, which can trap heat and feel synthetic — a difference that matters for comfort during long days in a fitted jacket.
- The jacket’s stretch is engineered into the weave — using high-twist yarns and a floating weave structure — rather than added elastane, which helps the fabric maintain the crisp, refined hand of a tailored woven instead of the synthetic feel common to elastane blends.
Recycled polyester lining vs traditional linings
- Compared to virgin polyester production, manufacturing this lining’s recycled fibers consumes 59% less energy and emits 71% fewer CO₂ emissions per ton, so the jacket’s sustainability story is backed by measurable upstream reductions rather than vague eco-claims.
- rPET’s dimensional stability results in a 1–3% shrinkage rate after repeated dry cleaning, so the lining holds its shape inside the jacket and does not pucker or distort the slim Stockholm fit over multiple seasons.
- The lining fabric is spun from recycled polyester derived from post-consumer plastic bottles — roughly 60 per kilogram of fiber — so the jacket's interior directly displaces virgin petroleum-based polyester and diverts waste from landfills, all while delivering identical durability and wrinkle resistance.
- Polyester’s inherent wrinkle resistance means the lining stays smooth and flat even after a long day of sitting, and unlike viscose, which can be prone to shrinkage and pilling if not properly treated, this recycled polyester requires no special handling — the jacket can be professionally dry cleaned as needed without loss of shape or crispness.
- With a moisture absorption rate of just 0.4%, the recycled polyester lining does not soak up perspiration — moisture instead dries rapidly from the fabric surface, keeping the jacket interior feeling dry through a warm commute or a long day at the desk, in contrast to viscose linings that can absorb up to 12% of their weight in water and may feel damp.
- Where viscose linings typically last 5–10 years with careful maintenance, polyester linings are rated for 8–15 years of service with much lower care demands — so this recycled polyester lining extends the jacket’s usable life, reducing the need for replacement and its associated environmental cost.

Q&A
3 answered- Can you provide the exact chest and waist measurements for each size of the Stockholm slim fit, and how does the fit compare to other brands' slim fit jackets?
- Exact chest and waist measurements per size aren't published, but suit jacket sizing typically aligns with chest measurement (e.g., size 40 = 40" chest). This Stockholm slim fit has a 7" drop, meaning the waist is 7" smaller than the chest [2]. Compared to other brands, it's similar to Suitsupply's Milano or Havana tailored fit (slim chest and waist) [14], and more fitted than H&M's Slim Fit blazer which offers slightly more room [4].
- What is the percentage of stretch in the fabric? Is it due to elastane content or the weave construction?
- The exact percentage of stretch isn't specified, and the fabric composition lists only responsible wool and polyester (from recycled bottles) without mentioning elastane [1]. This suggests the stretch likely comes from the weave construction (a stretch weave) rather than added elastane fibers.
- What are the recommended care instructions? Is it dry clean only, and can it be steamed at home?
- We recommend professional dry cleaning only, as is standard for wool-blend suit jackets. You can steam the jacket at home to refresh it between wears, but avoid machine washing, bleaching, or tumble drying.
