A clean, minimal long-sleeve crew neck tee built for everyday wear. Available in classic black, white, and heather grey, this relaxed-fit top features subtle tonal seam detailing along the chest and sleeves that adds quiet structure without breaking the understated aesthetic. Cut with a slightly boxy silhouette, it works equally well as a standalone layer or as a base under heavier outerwear.
Product Highlights
Relaxed, slightly boxy silhouette with a clean crew neckline
Tonal vertical seam detailing on the front panel and sleeves for subtle visual interest
Available in three versatile colorways: Black, White, and Heather Grey
Smooth, medium-weight jersey fabric with a soft hand feel
Ribbed crew neck collar for a neat, structured finish
Suitable for spring and autumn layering or standalone warm-weather wear
Fit & Styling
This tee is cut with a relaxed, slightly oversized fit — ideal for those who prefer a casual, unfitted silhouette. The dropped shoulders and boxy body pair naturally with straight-leg or wide-leg trousers, cargo pants, or denim. Wear it tucked half-in for a smart-casual look, or leave it untucked for a laid-back streetwear feel. The neutral colorways make it easy to build outfits around. Sizing runs true to the measurements provided; if you prefer a closer fit, consider sizing down one size.
Product Details
Fabric: 100% Cotton jersey, medium weight. The garment is constructed with flatlock-style tonal seaming on the front body panels and along the sleeve, giving it a refined, structured appearance. Crew neckline features a ribbed collar band. Long sleeves with clean, unfinished-style cuffs. Available in sizes M through XXL.

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.
