The highly breathable PEARL iZUMi Attack Hybrid Jacket protects us from the elements and at the perfect temperature as we ride on a cold, rainy day. The 3-layer polyester wind-blocking fabric on the body and arms limits the chill we feel from the chilly winds, while the lightweight stretch woven fabric on the underarms and waist allows heat to escape. PEARL iZUMi added three rear pockets to carry our essentials and keeps us visible in low-light conditions with BioViz reflective elements.
