evo.com | Nike Activewear Jackets > The Nike ACG Therma-FIT Wolf Grid Half-Zip Top is built for the moments when you're deep into a route, soaked in sweat, and the temperature is dropping fast. The checkerboard grid fleece does double duty: raised squares trap body heat while the low channels wick moisture and push it away from your skin, so you stay warm and dry without the clammy, waterlogged feeling that forces the early turnaround. Nike Therma-FIT ADV Nike Therma-FIT ADV technology combines heat-regulating fabric with advanced engineering and features to help keep you warm in cold-weather conditions. Flat Seams and Stitched Panels Through Shoulders and Underarms Elastic Hem and Cuffs Breathable Grid-Back Fleece Contouring checkerboard-patterned fleece feels soft and light on your skin. The raised square sections help store your body heat for warmth. The low square sections rest closer to the skin to help wick sweat through thin, breathable channels and away from your body.
