A laid-back American vintage aesthetic meets everyday wearability in this full-zip knit cardigan. Crafted in a soft, heathered knit body, the jacket-style sweater features a bold contrast ribbed polo collar in blue tones that sets it apart from standard zip-ups. A metal logo badge on the chest adds a subtle branded detail, while the ribbed cuffs and hem deliver a clean, structured finish.
Product Highlights
Contrast ribbed polo collar in blue stripe — a standout colorblock detail against the heathered body
Full-length metal zipper closure for easy on/off and adjustable coverage
Relaxed, boxy silhouette with dropped shoulders for a casual, oversized feel
Ribbed cuffs and hem for shape retention and a polished edge
Small metal logo badge at the chest for a refined, understated branding touch
Available in Heather Gray and Black — both with the signature blue contrast collar

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.
