The Demons Inside Long Sleeve Tee is built for those who wear their attitude on their sleeve — literally. Bold distressed lettering across the chest spells out the statement, framed by tribal flame artwork and a winged crest graphic that gives the piece a cryptic, underground edge. Claw-mark graphics tear across the front body, adding raw visual tension that sets this tee apart from anything basic in your rotation.
Gradient Crack-Effect Sleeves
The sleeves fade into a deep cracked-texture gradient — available in forest green on white or crimson red on black — creating a worn, fractured finish that looks intentional and worn-in from day one. The contrast between the clean body and the distressed sleeve ends gives the silhouette a layered, editorial quality without needing to add extra pieces.
Everyday Comfort, Relaxed Fit
Constructed from 100% cotton, this long sleeve tee is soft, breathable, and comfortable enough for all-day wear. The relaxed fit works well over joggers, under an open overshirt, or paired with cargo pants for a full streetwear look. The McCann branding and symbolic crown-dollar logo add finishing details that reward a closer look.

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.
