This men's long-sleeve sweatshirt combines the casual comfort of a classic crew-style pullover with the polished look of a polo collar. A contrasting blue plaid trim runs along the collar edge and button placket, creating a layered, fake two-piece effect that adds visual interest without extra bulk. Available in navy, black, and heather grey, it's a versatile piece suited for casual outings, weekend wear, or relaxed office environments.
Product Highlights
Polo-style collar with blue plaid contrast trim for a smart-casual aesthetic
Fake two-piece layered design — the look of a collared shirt underneath without the extra layer
Three-button placket at the neckline for adjustable ventilation and styling
Ribbed cuffs and hem for a structured, comfortable fit
Relaxed, slightly oversized silhouette suitable for a range of body types
Available in three versatile colorways: navy, black, and heather grey
Fit & Styling
This sweatshirt is cut in a relaxed, slightly oversized fit that sits comfortably through the chest and shoulders without feeling boxy. The ribbed hem keeps the shape tidy and pairs well with straight-leg jeans, chinos, or casual trousers. The polo collar elevates the look beyond a standard sweatshirt, making it easy to dress up slightly for casual social settings. For reference, size M measures 63 cm in length, 112 cm chest, 50 cm shoulder width, and 55 cm sleeve length. Size up if you prefer a more generous fit.
Product Details
Constructed from a midweight fleece-backed fabric, this sweatshirt is estimated to be approximately 65% Cotton and 35% Polyester, providing warmth, softness, and shape retention. The collar and placket feature a woven plaid fabric insert in blue tones. Long sleeves with ribbed cuffs. Pull-on style with a partial button placket. Available in sizes M, L, and XL.

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.
