The Seakoff "99" Long-Sleeve Mesh Jersey brings together classic athletic design and modern streetwear attitude. The oversized "99" graphic dominates both the front and back panels, printed on breathable perforated mesh for a look that commands attention. A clean circular chest logo adds a refined finishing touch above the number, keeping the front balanced and intentional.
Crafted for Comfort and Versatility
Built from 100% polyester mesh, this jersey is lightweight and breathable enough for all-day wear. The contrast satin-finish sleeve and shoulder panels create a premium two-texture look that elevates it beyond a standard sports jersey. The relaxed long-sleeve fit and V-neckline make it easy to layer over a tee or wear solo as a statement piece. Available in black with white graphics and red with white graphics, both colorways carry the same bold energy.
Easy to Style, Built to Stand Out
Pair it with wide-leg trousers, cargo pants, or denim for an effortless streetwear outfit. The "Growing" brand patch at the hem and the back wordmark add subtle branding details that reward a closer look. Whether you are heading to a game, a show, or just the street, this jersey delivers a confident, versatile fit.

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.
