Product Insights
This double-breasted navy suit jacket in virgin wool weave offers enduring formality through its peaked lapels and sharp silhouette, yet adapts to smart-casual contexts when worn open over a T-shirt or paired with a turtleneck. The Reykjavik semi-slim fit with a 7-inch drop, stretch weave, and double side vents ensures all-day comfort and a clean line in motion. Navy's versatility allows pairing with mid-grey, light blue, olive, or burgundy, while the wool's deep color and crease recovery maintain a polished appearance. Weekly brushing, careful stain treatment, and proper storage with a wide hanger protect the fabric, with dry cleaning recommended to preserve the wool and satin lining.
Verified claims
- Fabric
- Virgin wool's longer fibers resist fuzzing and improve crease recovery.
- Sizing
- Reykjavik fit uses a 7-inch drop, pairing size 40 jacket with size 33 trousers.
- Comfort
- Stretch virgin wool weave and double side vents provide all-day comfort.
- Formality spectrum
- Peaked-lapel jacket can be dressed down with a turtleneck or polo for smart-casual occasions.
- Side vents
- Double side vents keep the jacket silhouette sharp in motion and prevent fabric bunching.
- Color pairings
- Navy is the most versatile suiting colour after charcoal, pairing with mid-grey, light blue, olive, and burgundy.
- Versatility
- Worn open over a T-shirt for casual dates or with a turtleneck for evening smart-casual.
- Color longevity
- Virgin wool weave keeps the deep navy surface smooth and polished over time.
- Unbuttoned silhouette
- Open styling exploits waist suppression for a long V-shaped drape.
- Brushing
- Weekly soft-bristle brushing lifts dust and reduces need for dry cleaning.
- Stain treatment
- Blot water-based stains immediately with cold water; do not rub.
- Care
- Release wrinkles with a handheld steamer 6–8 inches from the fabric; if ironing is necessary, use the wool setting with a press cloth on the wool and only a cool setting with a press cloth on the satin lining.
- Storage
- Use a molded shoulder hanger at least 2 inches wide to prevent stretching.
- Dry cleaning
- Dry cleaning is recommended for this stretch virgin wool jacket to protect the fabric and lining.
- Suit separate wear
- This jacket is cut as a suit separate and is designed to be worn without its matching trousers, reading as an intentional blazer with cream chinos, mid-grey wool pants, or dark denim.
- Size 40 measurements
- Exact chest and waist measurements are not published for this jacket, but a size 40 Regular is described as corresponding to a 40-inch chest.
- Stretch composition
- The stretch in the Marlane virgin wool comes from a small elastane addition, typically about 2%, which lets the double-breasted front and slim armscye expand during movement.
