Using levels of mesh mapped to your body, you get ventilation where you need it, plus the comfort of fewer seams. It's pretty much the most comfortable thing you'll ever train in.

Features:

• New, softer knit fabric with engineered mesh ventilation, mapped to the places you need it most
• Nearly sew-free construction to eliminate chafing
• Material wicks sweat & dries really fast
• Reflective details for greater visibility on low-light runs
• Fitted: Streamlined fit that’s not too tight or too loose.
