This men's quilted down shirt jacket blends the relaxed silhouette of an overshirt with the warmth of a puffer coat. Featuring a classic spread collar, snap-button placket, and horizontal baffle quilting throughout the body and sleeves, it delivers serious insulation in a clean, versatile shape that works equally well as a standalone outer layer or a mid-layer over heavier knitwear.
Product Highlights
Horizontal baffle quilting across the chest, back, and sleeves for even heat distribution
Spread shirt collar gives a relaxed, American casual aesthetic
Snap-button front closure for easy on and off
Two patch pockets at the hip for everyday carry
Oversized, boxy fit sits comfortably over hoodies and thick sweaters
Available in deep Black and warm Coffee Brown for versatile seasonal styling
Fit & Styling
The jacket is cut in a deliberately oversized, boxy silhouette with dropped shoulders and a slightly curved hem. It is designed to be worn loose over mid-layers. Refer to the size chart: size M measures 71 cm in length, 120 cm chest, 53.5 cm shoulder width, and 55 cm sleeve length; size XXL measures 77 cm in length, 132 cm chest, 58 cm shoulder width, and 58 cm sleeve length. If you prefer a cleaner, more fitted look, consider sizing down one size. Pair with straight-leg trousers or relaxed denim and chunky sneakers for an American streetwear-inspired outfit.
Product Details
Shell and lining: 100% Polyester. Fill: 90% White Duck Down, 10% Feather. The quilted shell has a smooth, matte nylon-like finish that resists light wind. Snap buttons are tonal to the shell color. Available in sizes M through XXL.

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.
