NB Heat Grid Half Zip Pullover – Men's

For early morning runs or cool-weather training, the Heat Grid Half Zip is our pick when you need a lightweight layer that actually breathes. The grid fleece construction traps warmth without holding moisture, so you stay regulated when effort picks up. Reflective details and a half-zip collar round it out for low-light utility.

• Half-zip front closure lets you dial ventilation on the fly without stopping
