Size Up Steel "Sweat Activated" Tee


Aesthetic Comfort 

Combining Aesthetic with comfort, our shirts are made with our signature tri-blend fabric, ensuring a soft finish, with an aesthetic body-fit look. Giving you the best of both worlds. 

Premium Print
You can go home when you can read the shirt. Printed with our very own sweat-activated dye, the text becomes fully visible when you’re drenched. Ditch the clock, and go home when you can the text is readable. 

Traditional Fit
Our classic, traditional stitch makes it impossible to have a bad fit. Designed with the average joe in mind, this tee fits every body-type perfectly. That coupled with our extreme-stretch fabric gives you a perfect fit that highlights your muscle tone and body shape. 

Tri Blend Fabric
Our special tri-blend fabric is a fusion of cotton, polyester, and spandex. Making the shirt just the perfect amount of stretch to strength ratio. The tee moves fluidly with you, complimenting your motion, but is strong enough to take a beating. Synthetic fibers in the fabric are resilient to stretching, meaning they never lose their shape.

Easy Care
No more trips to the dry-cleaners, or hand-washing. Our shirts are made to be convenient and long lasting, and comfortable. 100% machine-wash safe and fit for the dryer. You can throw these shirts into the washer a hundred times and still have it looking as bright as the day you bought it 

Locally Sourced
Here at Size Up, we pride ourselves on our fair-trade policies. All our clothes are locally sourced, from fiber to stitch, everything is produced right here in the states. So you can relax knowing your clothes are 100% exploit-free.

Our signature tri-blend fabric requires less water to produce than ordinary cotton or cotton-polyester blends, making our clothes good for you and for you future generations.
