A classic American-inspired Harrington jacket reimagined with bold contrast collar detailing and a relaxed oversized silhouette. Available in four muted seasonal colorways — khaki, olive green, light blue, and cream — each version features a contrasting spread collar, full-length center zip, and embroidered patch graphics for a vintage workwear aesthetic with a streetwear edge.
Product Highlights
Contrast spread collar in a complementary accent color on every colorway
Embroidered and woven patch graphics on the chest — "CHILL" pennant flag or "COME" badge depending on colorway
Full-length center front zip closure with a small zippered chest pocket
Two large flap patch pockets at the hip for practical storage
Elasticated hem and cuffs for a relaxed, blouson-style fit
Twill-weave fabric with a subtle diagonal texture for structure and durability
Fit & Styling
This jacket is cut in an oversized, boxy silhouette that sits at the hip. The elasticated hem and cuffs add volume at the waist and wrists, giving it a classic Harrington blouson shape. It pairs well over a plain tee or lightweight crewneck sweatshirt. The contrast collar and patch detailing make it a statement outer layer — style it with straight-leg trousers or relaxed denim for a retro workwear look. Refer to the size chart: M fits a chest up to 144 cm, L up to 148 cm, and XL up to 152 cm.

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.
