This boxy stand-collar down jacket features a distinctive irregular grid-quilted exterior that sets it apart from standard puffer silhouettes. Filled with 90% white duck down, it delivers genuine warmth without excessive bulk, making it a practical choice for cold-weather commuting and everyday wear. Available in muted Grey and classic Black, the clean colorways keep the architectural quilting as the focal point.
Product Highlights
90% white duck down fill for lightweight, efficient insulation
Irregular grid quilting pattern on the front with curved panel stitching on the back for a structured, design-forward look
Stand collar with full-length zip closure for wind protection
Elasticated cuffs to seal in warmth and maintain a neat silhouette
100% polyester shell fabric with 100% polyester lining for durability and easy care

Fit & Styling
The jacket is cut with a relaxed, slightly oversized boxy fit that layers comfortably over knitwear and hoodies. The cropped-to-hip length keeps proportions balanced whether worn with straight-leg trousers, wide-leg pants, or denim. The stand collar sits high enough to protect the neck without requiring a scarf. Refer to the size chart: M (chest 126 cm / length 65 cm) through XXL (chest 138 cm / length 71 cm). Those between sizes or preferring a more fitted look may size down.

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.
