A heavy-weight, acid-washed long sleeve tee built for American streetwear aesthetics. The Demischolab graphic print sits across the chest in a faded, worn-in finish, while intentional ripped holes run along both sleeves and the raw hem — giving the shirt an authentically distressed look straight out of the bag. Drawstring ties at the hem add a subtle utility detail that sets this piece apart from standard long-sleeve basics.
Product Highlights
All-over acid wash with sun-faded gradient effect for a vintage, worn-in appearance
Deliberately distressed: oval rip holes along both sleeves and the hemline
Tonal Demischolab chest graphic with website and badge detail in a cracked, aged print
Drawstring ties at the hem for adjustable styling and added streetwear character
Oversized, relaxed silhouette with ribbed cuffs for a clean finish at the wrist
Available in acid-washed olive green and washed black colorways
Fit & Styling
This tee runs with an oversized, boxy fit — ideal for layering over a longline undershirt or wearing solo with cargo pants, wide-leg jeans, or distressed denim shorts. The dropped shoulders and extended body length give it a relaxed street silhouette. Refer to the size chart: size S measures 69 cm body length, 107 cm chest, and 63 cm sleeve length, scaling up through 2XL at 77 cm body length and 123 cm chest. If you prefer a more fitted look, size down one. The olive green colorway leans military-tonal, while the washed black reads darker and more urban.
Product Details
Fabric: 100% Cotton, garment-washed and enzyme-treated for a soft, pre-aged hand feel. The heavyweight construction holds its shape despite the distressed detailing. Crew neckline. Long sleeves with ribbed cuffs. Intentional rip distressing on sleeves and hem. Drawstring hem ties. Demischolab branded chest graphic. Available in sizes S–2XL. Note: measurements are hand-measured; a 1–3 cm variance is normal.

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.
