A bold take on the classic stripe, this oversized long-sleeve crew neck shirt pairs wide contrasting stripes with a relaxed, drop-shoulder silhouette. Available in black-grey and navy-red colorways, it features a small embroidered script logo on the chest and a large cursive brand graphic across the upper back — details that give it a streetwear edge without overpowering the clean stripe layout.
Product Highlights
Wide horizontal colorblock stripes in two colorways: black-grey and navy-red
Small embroidered logo on the left chest; large script graphic printed across the upper back
Relaxed oversized fit with dropped shoulders and a boxy body
Ribbed crew neckline for a neat, structured finish
Long sleeves with ribbed cuffs — suitable for spring and autumn layering
Woven brand label at the inner neckline
Fit & Styling
This shirt is cut with an intentionally oversized, boxy fit — size down if you prefer a more standard relaxed fit, or stay true to size for the full streetwear silhouette. The dropped shoulders and wide chest make it easy to layer over a long-sleeve base or wear alone. Pair the navy-red version with dark denim or black joggers for a bold contrast look; the black-grey version works well with neutral tones for a more understated outfit. The crew neck and ribbed cuffs keep the overall look polished despite the relaxed cut.
Product Details
This men's striped long sleeve shirt is constructed from a medium-weight cotton-polyester blend — approximately 90% Cotton, 10% Polyester — giving it a soft hand feel with light structure that holds the stripe pattern cleanly. The fabric has enough body to drape well on an oversized frame without feeling stiff. Available in sizes M through XXL. Refer to the size chart for chest, length, shoulder width, and sleeve length measurements before ordering.

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.
