The Spikyhead Long Sleeve Polo Shirt delivers a bold streetwear statement through its faux two-piece layered construction — a short-sleeve polo shell with an attached long-sleeve underlayer built into one garment. A large embroidered "SPIKYHEAD" wordmark dominates the chest, flanked by a heraldic crest badge and an embroidered Union Jack flag patch, giving the piece a distinctly British-inspired aesthetic popular in European and Asian street fashion.
Product Highlights
Faux two-piece design: polo collar shirt with integrated long-sleeve underlayer for an effortless layered look
Large front "SPIKYHEAD" embroidered or printed wordmark for high-impact branding
Heraldic crest badge and Union Jack flag patch on the chest
Three-button polo placket with spread collar
Relaxed oversized silhouette with ribbed cuffs on the inner sleeve
Available in classic Black and White colorways
Fit & Styling
Cut in a relaxed, oversized fit, this polo runs generously across the chest and shoulders — ideal for a casual drop-shoulder look. The layered sleeve detail adds visual depth without extra bulk. Pair it with slim or straight-leg trousers, cargo pants, or denim for a clean street-ready outfit. The structured collar keeps the look polished enough for casual social settings. Refer to the size chart: size M measures 65 cm in length, 112 cm chest, 51 cm shoulder width, and 63 cm sleeve length.
Product Details
This polo shirt is constructed from a medium-weight cotton-blend fabric — approximately 95% Cotton, 5% Elastane — providing comfortable structure with a slight stretch for ease of movement. The faux layered sleeve is sewn as a single garment piece. Embellishments include an embroidered crest badge, a woven Union Jack patch, and a bold chest graphic. Machine wash cold; lay flat to dry to preserve embroidery and print quality. Available in sizes M through XXL.

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.
