Bicep reps call for Under Armour's sleeveless, fitness-oriented HeatGear Armour Shirt for Men. Its HeatGear fabric stretches, wicks moisture, ventilates, and resists odor for performance-specific comfort.
HeatGear four-way stretch fabric
Stretch mesh underarm panels

UPF 30+ sun protection
No bad ;)
I bought it as a birthday present to my friend since he likes to run and go to the gym. The size I bought was M since he always used M size, but this Under Armour shirt is a little to stick to the body so I will say size are not fit based on standards from other brands, I think L size will have been the correct one for him.
