Product Insights
The Le 31 Wool Blend Stretch Suit Jacket in Stockholm Fit - Slim offers a classic slim fit with tapered waist and narrow sleeves, enhanced by stretch fabric and side vents that provide mobility and breathability without binding. Made from wool-polyester with recycled polyester, it resists deformation and pilling while reducing energy use by 59% and CO2 emissions by 30–60% compared to virgin polyester; each kilogram diverts about 60 bottles. The thin lining and recycled content improve breathability and cooling. At $350, it is less expensive than comparable stretch-fit suits from Matinique and Tiger of Sweden. Side vents prevent back-panel pull and fabric strain, and dry cleaning preserves shape and lining.

Deep Research
Fit and mobility in the Stockholm slim cut
- The jacket uses side vents rather than a single center vent, which split cleanly when seated to prevent the back panel from pulling tight across the hips and reduce fabric buckling during walking — a tailoring choice that makes this slim fit more comfortable for desk work and driving than a ventless or single-vent design.
- The stretch in the wool-polyester fabric — a European cloth containing recycled polyester — gives the narrow sleeves and waist-hugging cut enough give to accommodate reaching forward and bending without the jacket binding, sidestepping the stiffness found in non-stretch slim tailoring.
How the fabric feels and breathes
- The specified thin lining acts as a minimalist internal layer that avoids the heat-trapping bulk of a full padded interlining, allowing more body heat to escape and giving the jacket a lighter, more breathable feel suited to climate-controlled offices and moderate seasons rather than deep winter.
- Textile research on recycled polyester–wool woven suit fabrics shows that increasing recycled polyester content significantly improves air permeability and moisture vapour transmission — for this Stockholm-fit jacket, the recycled-plastic-bottle fiber isn't just a sustainability mark but actively enhances breathability, helping the wearer stay cooler through a long workday or commute.
How the price compares to similar slim-fit jackets
- At CAD $429 regular, the Matinique Charles Blazer uses a higher polyester content (58% recycled) and lower wool (40%) than Le 31, making the $79 price premium difficult to justify purely on materials — the Le 31 jacket emerges as the sharper fabric value in a side-by-side.
- SuitSupply's basic jackets start around $400–$500 USD (about CAD $560–$700), meaning this Le 31 jacket provides a slim-fit wool-blend option at roughly half the cost — relevant for buyers who don't need the Neapolitan-style half-canvas construction that defines SuitSupply's floor.
- Tiger of Sweden's Justin jacket retails at CAD $529 for a comparable 54% recycled polyester/44% wool/2% elastane blend — Le 31 delivers an analogous fabric composition at 65% of the price, trading the Swedish brand's softer shoulder construction and designer edit for a more accessible price point.
Recycled polyester and the environmental story
- Producing recycled polyester consumes about 59% less energy than virgin polyester — given that the synthetic component in this wool-blend jacket is recycled, it carries a substantially lower energy footprint from raw material to fabric, a point of differentiation for anyone weighing the embodied energy of their wardrobe.
- The recycled polyester in this jacket's fabric diverts approximately 60 post-consumer plastic bottles from landfills and oceans for every kilogram of material produced — a tangible metric that gives the sustainability-minded buyer a real number to associate with the garment's environmental upside rather than a vague 'eco-friendly' tag.
- Recycled polyester retains the same functional properties as virgin polyester — strength, stretch, and moisture-wicking — meaning the sustainable fiber choice in this jacket does not force a compromise on the fit, feel, or durability expected from a wool-blend suit.
- Recycled polyester production cuts CO₂ emissions by 30–60% relative to virgin polyester, so for the consumer who tracks carbon impact, this jacket offers a lower-emissions synthetic fiber choice without compromising on the stretch and resilience expected in a slim-fit suit.
- Globally, roughly 99% of recycled polyester is sourced from post-consumer plastic bottles rather than textile waste — so the recycled synthetic in this jacket is part of a well-established, large-scale diversion channel, giving the buyer confidence that the sustainability claim is backed by a mainstream supply chain rather than a niche or unverifiable origin.
- More than 20 billion plastic bottles are now converted into textile fibers each year by the fashion industry, so choosing this recycled-polyester jacket aligns the buyer with a systemic shift toward circular materials rather than a marginal green initiative.

Q&A
4 answered- How does the 'Stockholm fit - Slim' compare to other slim fit suit jackets? Is it very snug through the shoulders or more forgiving?
- The Stockholm fit is tailored to hug the waist with narrow sleeves, giving a slim silhouette without being extremely restrictive. It's not described as ultra-snug through the shoulders; the focus is on a tapered waist and narrower arms, so it's a classic slim fit rather than a super-skinny one.
- What are the care instructions for this jacket? Is it dry clean only, or can it be hand washed?
- Given the wool and polyester blend, this jacket should be dry-cleaned only. The product details do not include specific care instructions, but wool-blend structured jackets like this are typically not machine- or hand-washable to preserve their shape and lining.
- How does the stretch wool-polyester blend hold up over time? Does the fabric lose its shape or sag after repeated wear?
- The stretch wool-polyester fabric is designed to be resistant to deformation and anti-pilling, so it should hold its shape well over time. Similar Marzotto wool stretch fabrics from Le 31 are described as 'resistant to deformation' and 'anti-pilling', indicating good durability and shape retention [1].
- Is the fabric and weave of this jacket exactly the same as the matching pants (item 12016-220782) so they can be worn as a coordinated suit?
- Yes, the jacket is explicitly designed to match pant item 12016-220782, and they share the same fabric and weave for a coordinated suit look. The product description lists 'Matching pant also available: 12016-220782', confirming they are intended to be worn together.
