The McCann Brothers Double-Layer Graphic Long Sleeve Tee is a streetwear-forward oversized top built around a faux two-piece construction — a short-sleeve outer shell layered over a long-sleeve inner cuff, all cut from a single garment. The tie-dye washed grey and washed black colorways both carry a bold distressed motorsport-inspired graphic on the chest, featuring the "McCann Brothers" wordmark, a star-letter logo, and the slogan "A Calm Heart" alongside the motivational text: Action is the ladder to success — the more actions you take, the higher you climb. Additional branding hits appear on the sleeves and chest for a fully loaded, editorial look.
Product Highlights
Faux double-layer design: short-sleeve outer tee over long-sleeve inner cuff in one piece
Distressed motorsport graphic print with "McCann Brothers" wordmark and star logo
Available in tie-dye washed grey and washed black colorways
Oversized boxy silhouette with dropped shoulders and relaxed chest
Sleeve and chest branding details for a fully styled streetwear aesthetic
Plain back panel keeps the look versatile and easy to layer
Fit & Styling
This tee runs oversized by design — the chest measurements range from 114 cm at M to 126 cm at XXL, making it ideal for a relaxed, drop-shoulder street fit. Wear it as a standalone statement piece with wide-leg cargo pants or denim, or layer it under an open overshirt. The long inner sleeves add dimension without bulk. If you prefer a slightly more fitted oversized look, size down one; for maximum drape, stay true to size or size up.

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.
