Product Insights

The Le 31 Stretch Wool Suit Jacket (London Fit, Semi-Slim) is a tailored piece that requires careful maintenance: dry clean every 3–4 wears alongside trousers to prevent color mismatch, steam wrinkles, brush with a horsehair brush after each wear, and dab spills with cold water. To extend its lifespan, allow 24–48 hours rest between wears, limit wear to twice weekly, use a wide contoured wooden hanger, and store in a breathable garment bag. Its recycled polyester component offers a rare sustainability feature at a C$350 price point, delivering identical performance to virgin polyester while reducing energy and CO2 emissions. Jacket and trousers are sold separately for size flexibility.

Deep Research

Care tips for stretch wool jackets

A stretch-wool jacket like the Le 31 should be dry cleaned no more than every 3–4 wears, because the chemicals and mechanical agitation gradually degrade wool fibers and strip the fabric’s natural oils — over-cleaning can rob the jacket of its soft drape and cause it to look tired within a year.
Use a handheld garment steamer to smooth wrinkles and freshen the jacket between wears — the steam relaxes the wool fibers without the direct heat that can scorch the fabric or create shiny press marks, and the polyester content already helps the jacket resist creasing, so a quick steam is often all that’s needed to look crisp.
The wool fibers need at least 24–48 hours to release moisture and recover their shape memory after a full day’s wear; giving the jacket this downtime prevents the gradual sag and crease accumulation that break the clean lines of a semi-slim, stretch-wool jacket.
Since matching trousers are available for this jacket, every professional cleaning must include both pieces together; wool fades slightly with each solvent cycle, and cleaning the trousers more often than the jacket leads to a visible mismatch that invalidates the suit’s coherence.
When the jacket isn’t in rotation, store it in a breathable cotton or muslin garment bag — never plastic — and place a cedar block or lavender sachet inside to repel moths; plastic traps humidity and accelerates mildew, which can permanently damage the delicate wool and thin lining.
Hanging this jacket on a wide, shaped wooden hanger — never a wire or skinny plastic one — protects the precise shoulder structure that defines the London fit’s semi-slim silhouette; a collapsed shoulder line is impossible to reverse and instantly cheapens the garment’s look.
Wearing the jacket no more than twice a week in rotation with other tailoring is the single simplest way to extend its lifespan — this rotational rest prevents the accumulated stress that leads to permanent creasing and shoulder distortion, effectively doubling the garment’s useful life.
For small spills, immediate spot cleaning with a clean white cloth and cold water — dabbing gently without rubbing — removes most water-based stains without subjecting the whole jacket to dry cleaning; the wool’s scaly surface traps dirt quickly, so speed is key, and aggressive rubbing only grinds the stain in.
Always have the jacket professionally cleaned before packing it away for the warm months; moths are drawn to the residual body oils and food particles on unwashed wool, and a clean garment stored in a breathable bag dramatically reduces the risk of moth holes and musty odors when you retrieve it.
If ironing is unavoidable, use a low-temperature wool setting and place a pressing cloth between the iron and the fabric — the polyester in the blend can melt under high heat, and the wool surface develops an unnatural shine when the iron touches it directly.
A 30-second pass with a horsehair clothes brush after every wear lifts dust and surface debris off the wool weave before it can settle in — a small habit that preserves the jacket’s matte luster and stretches the interval between dry cleanings, which is especially valuable for a light grey shade that shows soil easily.

How eco-friendly is the recycled polyester?

Manufacturing the recycled polyester in this jacket’s stretch wool blend consumes 45–85% less energy than making virgin polyester, according to peer-reviewed lifecycle assessments, so the garment’s fabric-level energy footprint is substantially lower — a concrete, data-backed improvement over a conventional suit jacket.
Roughly 98% of recycled polyester in apparel originates from post-consumer PET bottles, not old textiles, so the recycled content in this jacket almost certainly began as discarded drink containers — a straightforward waste-to-fashion loop that avoids the dead-end downcycling of fabric-to-fabric recycling and gives the jacket a simple, truthful sustainability hook.
Recycled polyester fibers retain equivalent tensile strength and abrasion resistance to virgin polyester because the PET polymer structure is identical after processing, so the recycled component in this wool-blend jacket does not compromise the garment’s ability to hold its shape through repeated wear and dry-cleaning — making it as durable as any conventional polyester-wool suit.
Recycled polyester production cuts greenhouse gas emissions by 30–60% versus virgin polyester, so the jacket’s recycled content reduces its carbon footprint at the fiber level — a measurable climate benefit that a buyer can cite when comparing it to a similar jacket made with standard polyester.
The molecular structure of recycled polyester is identical to virgin polyester once spun into yarn, so the recycled content in this jacket’s stretch wool fabric is invisible to the touch — the soft drape, crease recovery, and elegant finish come from the wool component and the overall construction, not from the polyester’s origin, meaning no aesthetic or tactile compromise for a formal garment.

Value compared to other suit jackets

As a jacket separate with dedicated matching trousers (SKUs 12016-217212 and 12016-217211), it lets buyers mix jacket and trouser sizes independently — a practical advantage that sidesteps the fixed drop of a pre-sized suit and effectively delivers a closer-to-custom fit without the upcharge of a made-to-measure program.
The polyester in the wool blend is spun from recycled plastic bottles, giving the C$250–350 jacket an inherent sustainability credential — a rare material story in an entry-level tailored separate, where virgin synthetics or basic wool remain the standard, and typically found only at much higher price points.
