New Castelli Donna Dinamica Women's Jacket Large Brilliant Pink Gore-Tex. The Dinamica Jacket is Castelli’s warmest women’s jacket, designed for cozy riding on the coldest winter days. GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric all over, blocking out any wind and striking a perfect balance between superb warmth and breathability. The fleece lining is comfortable next to skin and lets out an excess heat and sweat with ease. The pattern of the jacket and high collar creates a close but not restrictive fit, helping you stay warmer but keeping comfort levels high.
