Fit & Styling
This hoodie runs oversized — the model wears a size that falls mid-hip with dropped shoulders and wide sleeves, consistent with a relaxed streetwear fit. It pairs naturally with straight-leg or cargo trousers for a clean American casual look. Those who prefer a more fitted silhouette may consider sizing down. Refer to the size chart: size M measures 66 cm in length, 122 cm chest, 64 cm shoulder width, and 54 cm sleeve length; size L measures 70 cm length, 130 cm chest, 66 cm shoulder, and 56 cm sleeve.
Product Details
Material: 80% Acrylic, 20% Wool blend — a composition typical of chunky intarsia knitwear offering warmth, shape retention, and a soft hand feel. Available in sizes M through XXL. Pullover style with no front zipper or kangaroo pocket. Three colorways available: Navy Blue, Burgundy Red, and Heather Grey.

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.
