The Seakoff BenchMarK Long Sleeve Polo brings together classic collegiate detailing and contemporary streetwear attitude. Bold front typography reading "BenchMarK — New Retro, Unique Street Style" anchors the chest, while an embroidered crest badge and gothic-script monogram logo add a refined, varsity-inspired character. Available in both black and white, this polo works equally well as a standalone statement piece or as part of a layered outfit.
Breathable Mesh Construction for All-Day Wear
Crafted from a lightweight performance mesh fabric, this polo offers genuine breathability without sacrificing structure. The open-knit texture is visible throughout the body, keeping airflow consistent whether you are wearing it solo or over a long-sleeve base layer. The classic spread collar and V-notch placket give it a clean, athletic silhouette that sits comfortably in a tailored relaxed fit.
Design Details Worth Noticing
Every element of this polo is intentional. The long sleeves extend to a fitted cuff, the hem sits at a cropped-to-relaxed length, and subtle woven label details appear at the lower body. The embroidered crest on the left chest features gold laurel branches and a red heraldic shield, adding a premium finishing touch that elevates the overall look. Pair it with wide-leg trousers, cargo pants, or layered over a fitted tee for a versatile, street-forward outfit.

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.
