A Better Performance Tee for 5XL Guys

Strongsize doesn’t “size up” a medium—we design around real 5XL measurements. Wider yokes, deeper armholes, and an extended hem create freedom of movement without extra bulk. Then we integrate a next-gen knit that wicks sweat in seconds and flexes in every direction. The result? A shirt that feels like your favorite athletic tee but looks crisp enough for a dinner reservation. Once you’ve experienced this blend of fit and function, stiff cotton button-downs become a distant memory.
