Every successful raw-denim jean brand eventually faces the jacket question. The trucker (Type III) is the default answer: iconic, fabric-forward, and priced 1.5–2× the jean. It is also the least forgiving garment in the denim line — a jacket that fits wrong cannot be cinched by a belt.
Weight by Season
| Fabric weight | Wearable season | Character |
|---|---|---|
| 9–11 oz | Spring–fall; layering in winter | Breaks in fast, drapes sooner |
| 12–14 oz | Three-season workhorse | Holds structure, classic choice |
| 14.5–16 oz | Fall–winter statement | Armor at first, sculpture after |
Sizing: The Zero-Forgiveness Zone
Jeans forgive at the waist; jackets forgive nowhere. Conventions that work:
- Size for a closed-front fit over one layer. The classic trucker is meant to button fully — spec chest ease accordingly (usually 10–12 cm over body measurement).
- Account for shrink — sanforized fabric still moves ~1%; unsanforized jacket programs should pre-soak before cutting or size up and say so.
- Arm length is the silent return driver. Test on riders, drivers, and desk workers before sealing the block.
- Publish actual measurements — the same discipline as jeans, worth double here.
Construction Details That Earn the Price
- Selvedge visible on the outseam and coin pocket — the whole point of the fabric; hiding it wastes the premium.
- Chain-stitched hems — the vintage roping effect, and the detail enthusiasts check for.
- Copper rivets at stress points, hidden or exposed by design, not accident.
- Vegetable-tanned patch that darkens with the jacket. Hardware guide here.
Season Planning Reality
A 14.5 oz jacket buys in fall and sells through winter; a 10 oz version buys in spring and layers all year. Launching one weight first? Match it to your market's dominant season, then widen. And unlike jeans, jackets age visibly — patina photos of a two-year-old trucker are the best marketing the category has ever had.
