A refined take on casual streetwear, this men's polo collar quarter-zip sweatshirt blends the clean structure of a polo neckline with the comfort of a heavyweight pullover. The half-zip opening adds versatility to the silhouette, while a subtle script graphic on the left sleeve gives it a modern American-casual edge. Available in light heather grey and black, it transitions effortlessly from weekend errands to low-key social settings.
Product Highlights
Polo-style spread collar with a quarter-zip closure for adjustable neckline styling
Script signature graphic printed on the left sleeve for understated branding
Relaxed, boxy silhouette designed for a comfortable oversized fit
Ribbed cuffs and hem for a clean, structured finish
Available in light heather grey and black — both with tonal sleeve detail
Suitable for spring and autumn layering over tees or under light outerwear
Fit & Styling
This sweatshirt is cut with a relaxed, slightly oversized fit — ideal for those who prefer a laid-back, streetwear-influenced silhouette. The polo collar elevates it slightly above a standard crewneck, making it easy to style with straight-leg trousers, chinos, or casual denim. For a clean look, leave the zip partially open. Size up if you prefer an even boxier drape; otherwise, select your standard size using the measurements below.
Product Details
Material: 80% Cotton, 20% Polyester fleece-back fabric. Polo spread collar with quarter-zip. Script graphic detail on left sleeve. Ribbed cuffs and hem. Pullover construction. Available in Black and Light Heather Grey.

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.
