Try the Best Performance Tee for 8XL Guys

Most “big sizes” simply scale up a pattern; Strongsize starts with 8XL on the drawing board. We mapped real customer measurements to create broader shoulder panels, a roomier chest, and an extended torso that won’t ride up when you reach overhead. Then we added four-way stretch yarns and micro-venting for airflow—so the shirt feels more like athletic wear than business attire. Slip it on once, and you’ll understand why bigger guys ditch stiff cotton button-downs for Strongsize performance fabric.

Flex-Ready Stretch & Wicking Fabric

Built from a high-tech blend that bends, rebounds, and pulls perspiration away in seconds. You stay dry, the shirt keeps its shape, and odor is kept in check—even on humid, high-activity days.

Precision Big & Tall Tailoring

Generous through the shoulders and biceps, subtly tapered toward the hem. No balloon effect, no tight pinch points—just a balanced silhouette that lets you move naturally.

Everyday Button-Down Freedom

Short sleeves, a modern collar, and a smooth placket give you license to dress it up with slacks or down with shorts. Travel, golf, casual Fridays—one shirt covers it all.

FAQ

What is the back length on an 8XL performance shirt?

Standard 8XL measures about 37.5″ from collar to hem. Our “Tall” version adds roughly 2″ in body length and 1″ in sleeve length for extra coverage when you sit, bend, or swing.

Can I layer this 8XL button-down under a blazer or jacket?

Yes - the lightweight knit adds minimal bulk, making it an ideal base layer beneath blazers, sport coats, or light outerwear. You stay cool and unrestricted.

Is the 8XL performance tee comfortable in hot weather?

Definitely. The moisture-transport fabric, micro-venting, and short sleeves work together to regulate temperature, keeping you fresh during sweltering commutes, outdoor events, and sun-soaked weekends.
