A clean, athletic-inspired track jacket built for everyday wear. Featuring a structured mock neck collar with contrast trim, bold diagonal colorblock panels at the shoulders and sides, and a full-length zip closure, this jacket brings a high-street edge to casual outfitting. Available in classic Black with off-white contrast and a light grey with black contrast, both colorways deliver a sharp, versatile look.
Product Highlights
Mock neck stand collar with contrasting inner trim detail
Diagonal colorblock panels on shoulders and side seams for a sporty, deconstructed aesthetic
Full-length front zip closure for easy on and off
Elasticated hem and cuffs for a secure, relaxed fit
Chest patch pocket and two lower front pockets for functional storage
Oversized, boxy silhouette suited to layering over hoodies or tees
Fit & Styling
This jacket runs with an intentionally oversized, relaxed silhouette — ideal for streetwear layering. The dropped shoulders and roomy body pair well with slim joggers, cargo pants, or straight-leg jeans. Size up if you prefer an even more relaxed drape; size down for a cleaner, structured look. The mock neck sits comfortably without a hood, making it a versatile transitional layer for spring and autumn. Both colorways work equally well styled with neutral basics or bold graphic tees underneath.
Product Details
Constructed from a smooth, lightweight woven shell of approximately 88% polyester and 12% spandex, giving the fabric a subtle sheen and gentle stretch. The elasticated hem and cuffs are finished in a ribbed-style elastic band. The jacket features raglan-influenced sleeve construction and contrast colorblock inserts sewn into the side and shoulder seams. Available in Light Grey and Black, 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.
