A laid-back American streetwear staple, this men's polo collar knit sweater pairs a classic rugby-stripe pattern with a relaxed oversized silhouette. The dark brown base is broken up by bold horizontal stripes in white, blue, and burgundy, giving it a retro vibe that works equally well for casual outings and low-key social settings. A three-button placket at the chest and a spread polo collar add a polished edge to the otherwise easygoing look.
Product Highlights
Polo collar with three-button placket for a smart-casual finish
Bold multi-stripe pattern in white, blue, and burgundy on a dark brown ground
Relaxed oversized fit with dropped shoulders for a comfortable, streetwear-ready silhouette
Long sleeves with ribbed cuffs and a ribbed hem for a clean, structured edge
Embroidered "Alive" logo detail at the chest
Versatile styling that transitions easily from campus to weekend wear
Fit & Styling
This sweater is cut with a relaxed, slightly oversized fit — ideal for layering over a basic tee or wearing on its own. The dropped shoulders and roomy chest give it a casual, unforced look. Pair it with slim straight jeans or chinos and clean sneakers for an effortless streetwear outfit. The polo collar also makes it easy to dress up slightly with tailored trousers. Refer to the size chart: size M measures 61 cm in length, 108 cm chest, 50 cm shoulder width, and 53 cm sleeve length.
Product Details
Constructed from a soft knit blend of approximately 60% acrylic and 40% nylon, this sweater delivers a smooth, slightly brushed hand feel with good shape retention across seasons. The stripe pattern is knitted directly into the fabric for a clean, consistent finish on both front and back. Available in 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.
