The Seakoff Archival Graphic Heavyweight Long Sleeve is a statement piece rooted in raw streetwear culture. The oversized black emblem graphic — a crescent, star, and curved symbol — dominates the chest with the kind of mysterious, worn-in energy pulled straight from underground crew tees and archival poster art. The acid-washed pink finish gives the fabric a lived-in, vintage character that only gets better over time.
Cropped Boxy Fit for Modern Streetwear Proportions
Cut in a boxy, cropped silhouette, this long sleeve hits the ideal contemporary streetwear proportion — not too oversized, not too fitted. The ribbed crewneck and dropped shoulders add structure, while the shortened length pairs naturally with high-waisted bottoms, cargo pants, or layered fits. The clean, plain back keeps the focus on the front graphic without distraction.
Heavyweight Cotton Construction
Made from 100% heavyweight cotton, this piece is soft yet structured with a satisfying weight that drapes well and holds its shape. The washed finish softens the fabric while adding visual depth to the pink colorway, making it feel like a genuine archival find rather than a mass-produced basic.

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.
