Under Armour’s Rush workout gear features minerals embedded in the fabric to reflect your body’s Far Infrared (FIR) heat ‘energy’ back into the muscles to create deeper warmth. That warming effect is supposed to translate to muscle-function gains so you can work harder and recover faster. 

Under Armour Rush Seamless Legacy Short-Sleeve Tee features

The well-fitting Seamless Legacy Short-Sleeve Tee harnesses Rush technology in a workout top that’s designed to handle your toughest sessions, whether you’re lifting, pushing watts in a spin class or legging it about town. 

Get the right workout footwear with the best gym shoes

Made from a soft-knit, four-way stretch fabric, it fits close and contours to your torso so there’s no baggy excess to get in the way of your movements. But it’s also not skin-tight, so even if you’re not 8% body-fat ripped, it’s still a forgiving look. The sleeves are cut relatively high, so it’s good for unrestricted upper body drills. The hem also hangs low enough to provide coverage even if you’re dangling from the chin-up bar. 

Pair your new tee with one of the best shorts for men

The tee feels light and comfortable against your skin. It has a nearly seam-free design that helps reduce chafe risk, along with strategically placed engineered mesh ventilation zones. Those are mapped to the places you need it most like across the chest and lower back.

That helps keep things cool and when you eventually do work up a sweat, the material wicks well and dries relatively quickly. Even on long, hot runs, it doesn’t suffer from the chafe-inducing sodden drag you can get with other tees.   

Want something longer? These are the best sweatpants

Overall, this is a good versatile workout T-shirt that’s ideal for most gym-floor workouts. It’s light and flexible enough for upbeat studio sessions and perfectly at home on endurance runs, too. 

The Seamless Legacy Short-Sleeve tee comes in six colours and five sizes from S to XXL.
