A refined take on American vintage workwear, this boxy zip-up jacket features a clean solid outer shell in rich brown or black, contrasted by a blue-grey or tan plaid flannel lining that peeks through the collar, hem, and cuffs for a polished faux-layered look. The result is a versatile piece that reads as two garments in one, delivering effortless old-money style with minimal effort.
Product Highlights
Faux two-piece design: solid outer jacket with a plaid flannel inner layer visible at collar, cuffs, and hem
Full-length metal zipper closure with a clean placket for a streamlined front
Two front welt pockets at the hip for everyday carry
Snap-button cuffs on the inner plaid layer for adjustable layering detail
Relaxed boxy silhouette with dropped shoulders for an on-trend oversized fit
Available in warm coffee brown with blue-grey plaid, and black with tan plaid
Fit & Styling
This jacket is cut with a boxy, slightly oversized silhouette — ideal for layering over a heavyweight tee, crewneck sweater, or slim-fit trousers. The dropped shoulder and generous chest measurement make it comfortable to wear over mid-weight knitwear. For a clean commuter look, pair the brown version with dark chinos and white sneakers; the black version works equally well with straight-leg denim. Size M measures 70 cm in length with a 118 cm chest — size up if you prefer a more relaxed drape, or stay true to size for a structured oversized fit.

How to Find Your Perfect Size — Every Time
How to Find Your Perfect Size — Every Time
Struggling to pick a size online? Here's a simple trick: instead of guessing, use a piece of clothing you already own — and love the fit of — as your reference point.
Step 1: Pick Your Reference Item Think of a T-shirt you've bought before that fit you perfectly. Find that order and pull up its size chart.
Step 2: Focus on Two Key Measurements For streetwear-style tees, two numbers matter most:
Chest width— too narrow and it'll feel tight
Length— too long and it'll look sloppy
💡 Tip:Size charts sometimes list "Chest" as theflat-lay widthinstead of the full circumference. Here's how to tell the difference:
Large number(e.g., 49in / 124cm+) → likely the actual chest circumference
Small number(e.g., 24in / 62cm) → likely the flat width (garment laid flat and measured edge to edge)
Step 3: Note Your Ideal Numbers Write down the chest and length measurements from your best-fitting shirt. Care about sleeve length or shoulder width too? Note those down as well.
Step 4: Match to Our Size Chart Now check Seakoff's size chart and pick the size whose measurements are closest to your notes. That's it — no more guessing.
Works for Everything This same method applies to hoodies, sweaters, jackets, and more. Do it once, and you'll be able to shop confidently, anywhere — every time.
