The Seakoff Zip Up Flannel Jacket delivers a striking blue-and-black check pattern with raw-edge distressed finishing throughout — at the hood, cuffs, and hem. The result is an intentionally undone, grunge-inspired aesthetic that feels both effortless and considered. A full-length silver zip runs down the centre front for easy on-and-off wearability.
Intricate Embroidery Front and Back
A subtle branded embroidery sits on the left chest, while the back features a large, detailed graphic of ornate crosses intertwined with roses — rendered in tonal stitching that stands out without overpowering the plaid base. The combination of classic tartan and gothic-inspired artwork gives this zip up flannel jacket a genuinely unique character that separates it from standard shackets.
Everyday Layering, Elevated
Cut in a relaxed, oversized silhouette, this flannel jacket layers naturally over hoodies, long-sleeve tees, or lightweight knits. The attached hood adds practical coverage while reinforcing the streetwear aesthetic. Made from a cotton-rich athletic blend, it offers a soft, comfortable hand feel suitable for all-day wear. Ideal for casual outings, urban commutes, or festival layering.

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.
