The Seakoff "Savage Base" plaid button up shirt is built for those who wear their personality loud. Available in two striking colorways — deep navy-green tartan and rich red tartan — each shirt features a contrast camouflage collar that cuts through the classic plaid pattern with a raw, military-inspired attitude. The result is a piece that feels both heritage and street-ready at the same time.
Statement Graphics, Front and Back
The back of each shirt is anchored by bold embroidered lettering reading "E.T.S — Liberate Oneself — Savage Base" alongside a winged eagle graphic, making it a true statement piece even from behind. The front chest features a woven patch badge and a functional chest pocket, adding utility to the visual detail. Button-up closure and short sleeves keep the silhouette clean and wearable across seasons.
Relaxed Fit, Pure Cotton Construction
Crafted from 100% cotton, this shirt offers a breathable, comfortable wear with a relaxed fit that works well over a plain tee or worn open as a layering piece. It pairs naturally with cargo pants, wide-leg denim, or shorts for an effortless streetwear look. Sizes run from M to XXL with detailed measurements available to help you find your ideal fit.

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.
