Stay warm and dry during your intense workouts with the sweat-wicking Nike Pro Long-Sleeve Top. Built to fit close to your body, this top works perfectly as a base layer.
CHEST - With your arms relaxed at your sides, measure around your chest at the armpits, over the fullest part of your chest and shoulder blades, keeping the tape horizontal.
WAIST - Measure around your waist where you normally wear your pants, keeping the tape horizontal.
If your measurements fall between two sizes, choose the smaller size for a tighter fit or the larger size for a looser fit.
