Polyester Zipper closure Hand Wash Only The built-in shock cord and easily packable design allow you to securely stow this jacket to your bars or a pack quickly when needed. Durable Water Repellent (DWR) is a finish or coating added to Giro fabrics to make them water-resistant so they can shrug off rain, snow, and damp conditions. The Core Ventilation Panels are cleverly designed to double as hand pockets, allowing you to quickly dump excess heat from inside the jacket while also offering a convenient option for extra storage or warming hands when needed. Back Exhaust Ventilation allows warm air inside the garment to escape, enhancing thermal regulation, moisture management and overall comfort as you ride. The lightweight 15,000mm waterproof fabric is fully seam sealed and further enhanced with a DWR coating to shed water and grime while maintaining 15,000g/m2 of breathability thanks to laminated materials and strategically placed exhaust venting. The cut is relaxed without being baggy, perfect for layering over jerseys or tech tees, and it includes an adjustable hem, two zippered hand pockets and genuine 3M Reflective highlights for visual pop in low light conditions.
