Product Insights
The Banker-Stripe Suit Jacket from Le 31 offers a semi-slim Reykjavik fit with a 7-inch drop that tapers the waist, ideal for men with a 7-inch chest-waist difference, and pairs with matching trousers using the same drop to maintain the silhouette, though this drop pairs a 40R jacket with size 33 trousers as a tradeoff. Constructed from Italian Super 100s wool by Marzotto, it provides a soft, clean drape, and includes a satiny lining for comfort. At $450 CAD, it undercuts comparable licensed-brand suits by $150 or more and comes with complimentary in-store tailoring. The matching trousers are available separately to avoid dye-lot mismatch, but the medium-weight wool runs warm, best for moderate climates, though it can be worn as a blazer with lighter trousers.
Verified claims
- Fit
- Semi-slim Reykjavik fit uses a 7-inch drop to taper the waist; it suits men whose chest-waist difference is around 7 inches, with tailoring accommodating up to 1 inch of variation.
- Drop
- Reykjavik has a 7-inch drop, pairing a 40R jacket with size 33 trousers.
- Mill heritage
- The shell is 100% Super 100 pure wool by Marzotto, woven at its 180-year-old Italian mill, giving the jacket a soft hand and clean drape.
- Price advantage
- At $450 CAD, this jacket with Italian wool and peaked lapels is $150+ less than comparable licensed-brand suits.
- Matching set
- A matching banker-stripe pant is available separately, avoiding dye-lot mismatch if bought later.
- Fabric
- Italian Super 100s wool by Marzotto with a satiny lining (53% polyester, 47% viscose).
- Tailoring
- Simons stores offer in-house tailoring for the Reykjavik jacket, including sleeve length and waist nip adjustments.
- Seasonality
- Listed as a fall/winter jacket, but its Super 100 wool is mid-weight (roughly 280–340 GSM), making it suitable for year-round use in moderate climates; the dense banker-stripe weave leans toward the warmer end of that range.
- Satin lining
- Satin lining reduces friction on shirt fabrics, improving comfort.
- Formal silhouette
- The semi-slim Reykjavik fit's double-breasted front with peaked lapels and side vents gives the jacket a formally bold, business-appropriate silhouette typically found at higher price points.
- Fit range
- The Reykjavik fit is the only semi-slim double-breasted cut Le 31 produces, so it is the fitted choice for a double-breasted office suit.
- Color options
- Offered in two colorways: taupe and blue. The blue reads as a classic navy banker stripe, and there is no charcoal option.
- Size measurements
- Simons publishes body measurements for this jacket: target chest runs 36–48 in (91.5–122 cm), natural waist 29–39 in (73.5–99 cm) for sizes 36–46; shoulder width is not published.

| Banker-Stripe Suit Jacket Wool Weave By Marlane Reykjavik Fit - Semi-Slim: Choose this if you want a double-breasted, semi-slim jacket with a waist-narrowing silhouette, wide peak lapels, and a classic banker-stripe pattern. It is cut from Super 100 pure virgin wool in an Italian weave by Marzotto with a thin satiny lining, and a matching pant is available to complete the suit. Note that long sizes (42 and 44) are listed only in the Taupe color, not Blue.[1,2,3,4] | Minimalist Double-Breasted Suit Jacket Antwerp Fit - Relaxed: Choose this if you want a relaxed, double-breasted blazer with a minimalist look, featuring peaked lapels, tonal buttons, welt pockets, and a centre vent in a smooth matte fabric. It suits shoppers who prefer easy-wearing stretch construction, with a shell of 68% recycled-bottle polyester, 29% viscose, and 3% elastane plus a satiny lining. It comes in regular sizes 34 through 46 in Black or Navy/Midnight Blue, though the fabric is polyester-viscose rather than wool, which matters if you prefer natural fibers.[5] | Oversized Double-Breasted Suit Jacket Imported From Seoul: Choose this if you want an oversized, boxy double-breasted jacket with dropped shoulders, wide notched lapels, and a straight hem falling past the hips for a relaxed, fashion-forward silhouette. It comes in Black or Brown in sizes Small to Large, made of thick polyester-rayon fabric with a bit of spandex and a fine satiny lining. Note that the main material is synthetic (80% polyester, 16% rayon, 4% spandex), which matters if you prefer natural-fiber suiting.[6,7,8,9] |
