When the temperature drops but the training schedule doesn't, the Nike Boys' Dri-FIT Miler Half Zip Top keeps young athletes moving comfortably through every mile. Dri-FIT technology pulls sweat away from the skin and accelerates evaporation, so even hard-working sessions in the cold don't leave him feeling damp and weighed down. The half-zip collar lets him dial in his ventilation on the fly, opening up when the pace picks up and locking in warmth when the wind picks up. Built-in thumbholes keep sleeves snug and in place, eliminating that annoying mid-run slide so he can stay focused on the run instead of his gear.
