A bold American streetwear-inspired track jacket featuring gothic "Black Energy" lettering across the chest, a waving US flag graphic, three-stripe sleeve detailing, and an all-over iron cross print on the collar, cuffs, and hem band. The full-length zip closure and stand collar give it a clean athletic silhouette, while silver snap buttons along the side seams add a customisable, deconstructable edge. Available in heather grey and sky blue.
Product Highlights
Gothic "Black Energy" chest lettering with US flag and star-circle badge graphics
Three-stripe contrast sleeve taping in classic track jacket style
All-over iron cross jacquard or print on collar, cuffs, and ribbed hem band
Full-length zip with mock/stand collar for a structured athletic look
Silver snap buttons along both side seams for a customisable fit
Relaxed oversized silhouette suitable for unisex wear
Fit & Styling
The jacket runs with an intentionally oversized, boxy fit — size down if you prefer a more fitted look. The model wears a size that falls mid-hip, layered open over a striped long-sleeve tee and paired with wide-leg cargo trousers and chunky boots, which captures the American retro-athletic aesthetic well. The stand collar sits high and structured when zipped. Both colourways — heather grey and sky blue — work equally well as a statement outer layer over basics or as part of a coordinated tracksuit-inspired set.
Product Details
Fabric composition: approximately 80% Cotton, 20% Polyester fleece-back jersey. The heather grey colourway has a marled cotton texture; the sky blue colourway has a smoother face. Ribbed cuffs, collar lining, and hem band feature the repeating iron cross motif. Side snap buttons run from underarm to hem. Sizes available: S, M, L, XL. All measurements are garment measurements in centimetres.

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.
