A bold American-vintage streetwear zip-up hoodie featuring an oversized argyle diamond graphic print across the chest, circular lettering, and a plaid flannel-lined hood. Available in heather grey and black, this full-zip hoodie blends retro athletic aesthetics with relaxed everyday wearability.
Product Highlights
Full-zip closure with a smooth metal zipper running the full length of the front
Large argyle diamond graphic with distressed figure illustrations and circular text print on both chest panels
Plaid flannel lining inside the hood — black plaid on grey, burgundy plaid on black
Plaid accent tabs visible at the side pockets, adding a layered vintage detail
Ribbed cuffs and hem for a structured, comfortable fit
Relaxed oversized silhouette suited to layering over tees or lightweight shirts
Fit & Styling
This hoodie is cut with a relaxed, slightly oversized fit — the model wears it with wide-leg sweatpants for a casual streetwear look. The chest graphic is bold and symmetrical when the zip is closed, splitting across both panels when open. It works well as a standalone outer layer in mild weather or over a crewneck in cooler temperatures. The flannel-lined hood adds a cozy detail that reads well when the hood is worn up. Size up if you prefer a more exaggerated drop-shoulder silhouette; your regular size gives a clean relaxed fit.
Product Details
Material: 80% Cotton, 20% Polyester fleece construction. Available in Heather Grey and Black. Sizes M, L, and XL. Hood interior lined with woven plaid flannel fabric. Side pockets with plaid accent trim. Full-length front zip. Ribbed cuffs and waistband.

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.
