This men's acid wash sweatshirt delivers a bold deconstructed aesthetic through its faux two-piece construction: a washed cotton body with a structured mock-neck silhouette sits over a contrasting corduroy long-sleeve underlayer, all engineered as a single garment. The result is a post-apocalyptic, American streetwear-inspired look that requires zero layering effort. Available in washed black with taupe corduroy and washed grey with charcoal corduroy.
Product Highlights
Faux two-piece design — outer short-sleeve body and inner long corduroy sleeves constructed as one piece
Acid/enzyme washed fabric for a lived-in, vintage distressed appearance
Contrasting corduroy ribbed sleeves add texture and visual depth
Structured mock crew neckline with a slightly raised collar
Center-back seam detail and front vertical panel seam for a deconstructed silhouette
Relaxed oversized fit suitable for layering or wearing as a statement piece
Fit & Styling
Cut with an oversized, boxy silhouette that sits comfortably on the shoulders and through the body. The extended corduroy sleeves reach the wrist for full coverage. This piece works well paired with straight-leg or cargo pants and chunky sneakers or boots to complement the post-apocalyptic streetwear aesthetic. The contrasting two-tone colorways — washed black with taupe or washed grey with charcoal — make it easy to build a tonal, layered outfit without extra pieces. Sizing runs generously; refer to the size chart for chest and shoulder measurements before ordering.

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.
