This mens long sleeve sweater polo combines a classic polo collar with a bold vertical stripe jacquard knit construction. The contrast navy and heather grey stripes run the full length of the body, creating a textured, dimensional look that sits between casual knitwear and smart-casual dressing. A four-button half-placket at the chest adds structure and easy on/off versatility, while ribbed cuffs and a ribbed hem provide a clean, polished finish.

Classic spread polo collar with solid navy ribbed trim
Four-button half-placket for adjustable neckline styling
Ribbed cuffs and hem for a neat, fitted finish at the edges
Relaxed, slightly oversized silhouette suitable for layering
Textured loop-yarn stripe detail adds visual depth and warmth
Fit & Styling
This sweater polo is cut in a relaxed, slightly oversized fit that works well over a slim tee or worn alone. The dropped shoulders and generous chest measurement make it comfortable for everyday wear through spring and autumn. Pair it with straight-leg trousers or dark denim for a smart-casual look, or layer it under a light jacket on cooler days. The polo collar keeps the overall aesthetic elevated without being overly formal. Refer to the size chart: M fits chest up to 116 cm, L up to 120 cm, XL up to 124 cm, and XXL up to 128 cm.
Product Details
Fabric composition is approximately 60% acrylic, 30% nylon, 10% wool blend, consistent with the textured loop-yarn jacquard knit construction visible in the product images. The garment features a full vertical stripe pattern across the body and sleeves, a solid navy ribbed collar, cuffs, and hem band, and a four-button half-placket closure. Available in Navy Stripe across sizes M through XXL.

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.
