A laid-back take on the classic polo, this long sleeve mens polo shirt features bold horizontal stripes and an open V-notch collar for a relaxed, vintage-inspired look. Available in black-grey and grey-white stripe colorways, it pairs easily with jeans, chinos, or casual trousers for an effortless streetwear or smart-casual outfit.
Product Highlights
Horizontal stripe pattern in two colorways: black/grey and grey/white
Open V-notch polo collar — no buttons required for easy on/off
Long sleeves with a relaxed, oversized silhouette
Contrast solid collar panel adds a clean, structured detail
Versatile styling — works for casual outings, street style, or light sport
Available in sizes S through XL with generous chest and shoulder measurements
Fit & Styling
This shirt is cut with a relaxed, slightly oversized fit — the chest measures 110 cm at size S and scales up to 122 cm at XL, making it comfortable to layer or wear on its own. The dropped shoulder and boxy body give it a contemporary streetwear feel. Style it untucked over slim-fit jeans or joggers. The grey/white version reads clean and minimal; the black/grey version leans more graphic and bold. Both work well across spring and autumn temperatures.
Product Details
Fabric composition: approximately 60% Cotton, 40% Polyester — a mid-weight blended jersey that gives the fabric its slightly textured, slubbed stripe appearance visible in the product images. The collar is finished in a smooth contrast fabric. Brand label: Chanyou. Care: follow garment label instructions.

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.
