This men's long sleeve button-up shirt draws from classic American moto and racing aesthetics, featuring bold colorblock panels across the chest and sleeves, contrast piping trim, and an embroidered "Gatherlab EPS" badge on the front. The relaxed, oversized silhouette and spread collar give it a laid-back vibe that works equally well as a standalone shirt or an open overshirt layered over a tee.
Product Highlights
Colorblock chest yoke and sleeve panels in contrasting tones — red on black or navy on grey
Embroidered "Gatherlab EPS" shield badge on the left chest for a retro racing team look
Oval logo patch on the right chest adds an authentic motorsport detail
White contrast piping outlines the yoke seams for sharp visual definition
Full button placket with matching tonal buttons for a clean finish
Plain back panel keeps the silhouette versatile and easy to style
Fit & Styling
Cut in a relaxed, boxy fit with a dropped shoulder and generous chest measurement — the size chart shows 112 cm chest at size M, making this an intentionally oversized piece. It suits most body types and is designed to be worn untucked. Pair it with slim straight jeans or cargo pants and chunky sneakers to lean into the American streetwear aesthetic. Works as a lightweight overshirt in spring and autumn layering.
Product Details
Shell fabric is a smooth woven construction, estimated at 65% Polyester, 35% Cotton, giving the shirt its structured drape and clean colorblock edges. Available in Black/Red and Grey/Navy colorways. Sizes M through XXL. Brand label reads "Savage Base." Back hem features small side vents for ease of movement.

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.
