The Seakoff "7" Colorblock Mesh Jersey delivers a clean, sport-inspired look built for everyday wear. The white front body pairs with bold black contrast raglan sleeves, creating a sharp two-tone silhouette that moves effortlessly from casual outings to active use. A striped diagonal "7" graphic sits prominently on both the front and back, giving this jersey an unmistakable identity on and off the field.
Breathable Mesh Construction
Crafted entirely from 100% polyester mesh, this jersey prioritizes airflow and lightweight comfort. The open-weave fabric keeps you cool during movement while maintaining a structured, polished appearance. The relaxed long-sleeve fit allows easy layering over a base tee or under a jacket, making it a versatile piece across seasons.
Details That Define the Look
Chest logo accents and subtle body paneling add dimension without overcomplicating the design. The V-neckline keeps the profile clean and wearable, while the contrast sleeve construction reinforces the sporty colorblock aesthetic. The reverse side features a grey body with navy raglan sleeves, effectively giving you two distinct colorways in one jersey.

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.
