The SEAKOFF Half Zip Knit Sweater brings vintage Americana energy into your everyday wardrobe. A large star-and-stripe flag graphic spans the chest in a jacquard-knit construction, rendered in deep burgundy, crisp white, and royal blue against a soft grey body. Contrasting burgundy sleeves and a matching mock-neck collar give the piece a striking two-tone look that stands out without trying too hard. White star accents near the cuffs add a finishing detail that ties the whole design together.
Soft Texture, Structured Fit
Crafted from a blend of polyester, acrylic, nylon, and PBT, this half zip knit sweater delivers a plush, fuzzy surface that feels warm and comfortable against the skin. Ribbed cuffs and a ribbed hem keep the silhouette clean and structured, while the relaxed unisex cut offers room to move and layer freely. The half-zip stand collar lets you dial in your warmth and style — wear it fully zipped for a sleek look or open for a more casual feel.
Easy to Style, Built for Everyday Wear
This sweater pairs naturally with straight-leg jeans, cargo pants, or joggers for an effortless streetwear outfit. It works equally well as a standalone layer or under an oversized jacket on colder days. Available in sizes M through XL with a relaxed unisex fit, it is designed to suit a wide range of body types and styling preferences.
Frequently Asked Questions
Is this half zip knit sweater true to size?
The fit is relaxed and unisex. Refer to the size guide — chest measurements range from 48 inches at size M to 51 inches at size XL — and size down if you prefer a more fitted look.
Is the flag design embroidered or knitted into the fabric?
The flag graphic is a jacquard-knit pattern, meaning it is woven directly into the fabric rather than applied as a patch or print.
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.
