This oversized puffer jacket features a bold diamond-quilted exterior that adds visual depth to a clean, minimal silhouette. Built for cold-weather wear, it pairs a stand collar with a full-length zip placket and two front slip pockets, delivering a streetwear-ready look across five versatile colorways.
Product Highlights
All-over diamond chevron quilting for a structured, textured appearance
Stand collar with zip-through placket for wind protection
Generously padded fill for warmth in cold winter conditions
Two front welt pockets with ribbed trim detail
Ribbed cuffs at the sleeve hem for a secure, comfortable fit
Available in five colors: Off-White, Black, Coffee Brown, Blue, and Olive Green
Fit & Styling
The jacket is cut in an oversized, boxy silhouette that sits at the hip. It layers comfortably over hoodies or thick knitwear without feeling restrictive. The clean, logo-free design makes it easy to style with joggers, cargo pants, or denim. The stand collar frames the face well when worn zipped up. Refer to the size chart — the chest measurements run generous, so size down if you prefer a more fitted look.

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.
