Built to support your personal best WOD or some quality time in the outdoors, the Max Effort brings it as much as you do. The knit and woven polyester construction not only moves with you, it makes up the perfect study in contrasts. And the underarm gusset frees up your arm motion when you need it most. Wicking and anti-odor properties reward your max effort by helping your body stay as cool and dry as possible. And reflective taping and logo add elements of safety to this smart shirt.
