The Seakoff Color-Block Panel T-Shirt redefines the basics with purposeful design. Curved contrast seam lines divide the body into distinct panels, creating a subtle architectural quality that sets this tee apart from standard everyday styles. The result is a clean, tech-inspired silhouette that works just as hard off-duty as it does on the street.
Relaxed Fit Built for Daily Wear
Cut in a relaxed oversized fit with a crew neckline and short sleeves, this tee is designed for all-day comfort without sacrificing shape. The 100% cotton construction keeps things breathable and soft against the skin, making it an easy go-to for layering or wearing solo. Available in a bold black-and-grey colorway and a muted yellow-green tone, both designed to pair effortlessly with joggers, cargo pants, or denim.
Sharp Details, Minimal Aesthetic
Visible curved seam construction and tonal color-blocking give this shirt a considered, intentional look without relying on logos or graphics. Whether you are building a techwear-influenced outfit or simply upgrading your casual rotation, the Seakoff panel tee delivers a refined edge that is easy to wear and hard to overlook.

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.
