XL Performance Shirts for Men

Ready to retire stiff cotton button-downs? Our XL Performance Shirts bring athletic comfort to a polished short-sleeve silhouette - engineered from the collar down for men who need just a bit more room without sacrificing style. Lightweight stretch fabric, rapid sweat-wicking, and wrinkle resistance let you power through meetings, plane rides, and patio dinners in total ease.

A Custom Tailored Performance Tee for XL Sizes

At Strongsize, XL isn’t an afterthought - it’s a starting point. We mapped real XL proportions to create extra shoulder width, a relaxed chest, and a slightly extended hem that keeps you covered when you reach or bend. Then we wove in four-way stretch microfibers that release heat and moisture faster than standard poplin. The result is a shirt that looks crisp, feels like activewear, and moves as hard as you do—office to off-grid.

Ergonomic XL Tailoring

Strategic panel shaping eliminates tight seams under the arms and bulk at the waist, giving you a trim profile with full range of motion.

4-Way Stretch Knit

Our proprietary blend draws perspiration off your skin and evaporates it in a flash. Plus, built-in flex threads bounce back wear after wear—no saggy elbows or stretched-out collars.

Flexible Style From Office to Out with Friends

A modern spread collar, hidden button loop, and smooth placket make it easy to dress up with slacks or dial down with shorts. One shirt, countless contexts.

FAQ

Will I need to iron or press this shirt?

Rarely. A quick tumble on low or a pass with a handheld steamer erases most travel creases. For razor-sharp lines, a warm iron works—but you’ll likely skip it.

What’s the center-back length on an XL vs. XL-Tall?

Standard XL measures about 32″ from collar seam to hem. XL-Tall adds roughly 2″ in body length and 1″ in sleeve length for extra coverage.

How should I wash and dry to keep the tech fabric performing?

Machine-wash cold, turn inside out, and skip fabric softener (it can block the wicking channels). Tumble dry low or hang—colors stay true and the stretch rebounds wash after wash.
