Trust your instincts. Made for high-output days and built to handle shifting temps, sudden gusts, and demanding terrain, the Tribrid ½ Zip is an essential piece for anyone serious about their time outside. Warm yet breathable, the gridded fleece insulation traps heat while releasing excess moisture, and wind-resistant Windblock panels shield you from the elements without adding bulk. Mobility stretch panels flex where you need it most, and the chest zip pocket with internal phone sleeve keeps essentials secure. Active Fit sits close without clinging, ideal as a mid-layer or standalone piece.
