Magpul MAG1399-001-XL Unfair Advatange Black Cotton/Polyester Short Sleeve XL
The Magpul Unfair Advantage short-sleeve shirt brings the same mission-driven design philosophy Magpul applies to rifles and tactical gear into everyday wear. Built from a 60% combed ring-spun cotton and 40% polyester blend, this crew-neck tee balances comfort with durability—soft enough for all-day wear, tough enough to handle the demands of shooters, hunters, and outdoor enthusiasts who refuse to compromise. Whether you're at the range, in the field, or anywhere in between, it's the kind of simple, well-made piece that works as hard as you do.
The construction reflects Magpul's attention to detail: double-needle stitching reinforces the hems and sleeves, so seams stay intact through heavy use, repeated washing, and the kind of wear that separates quality apparel from disposable basics. The cotton-poly blend dries faster than pure cotton and resists wrinkles, making it practical for travel, camping trips, or days when you're in and out of gear. True to the brand's no-nonsense aesthetic, the Unfair Advantage design comes in classic black—a color that works with any kit and never goes out of style.
This is apparel designed by people who understand the outdoor and shooting lifestyle, not fashion marketers guessing at what you need. If you value gear that's made to perform and built to last, this short-sleeve shirt earns its place in your rotation.
