This men's long sleeve shirt from Extreme Cause combines a washed, distressed cotton body with contrasting plaid flannel sleeves for a faux two-piece layered look. The band collar, three-button henley placket, and intentional worn-in finish give it a relaxed streetwear edge that works across casual and transitional seasonal outfits.
Product Highlights
Faux two-piece construction: solid washed body with contrasting plaid flannel sleeves for a layered effect without the bulk
Distressed, acid-washed finish on the body creates a vintage, worn-in aesthetic
Band (mandarin) collar with a three-button henley placket at the chest
Pintuck detail stitching runs vertically down the front panel for added texture
Available in Black with red plaid sleeves and Olive with dark khaki plaid sleeves
Relaxed oversized silhouette suited to spring and autumn wear
Fit & Styling
The shirt is cut in a relaxed, slightly oversized fit — roomy through the chest and shoulders with a straight hem that sits at the hip. It pairs naturally with slim or straight-leg trousers, cargo pants, or dark denim. The plaid sleeve contrast makes it a standalone statement piece; wear it open over a plain tee or as your outer layer on mild days. Refer to the size chart: chest circumference ranges from 114 cm (S) to 126 cm (XL), with shoulder widths from 48 cm to 51 cm.

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.
