SIZING: Castelli products have a close-to-the-body fit to maximize aerodynamics and performance. For a less compressive feel, or if your measurements fall between sizes, we recommend that you size up.
IDEAL FOR: Cyclists seeking a versatile jacket that that can be used as a light shell in mild weather, or in frigid conditions by adding a thermal layer underneath.
FRONT FABRIC: Castelli-exclusive Gore-Tex Windstopper Infinium 205 Warm brushed water-resistant fabric on front-facing surfaces to block wind and keep you warm.
REAR FABRIC: This Jacket features a different rear Gore-Tex Windstopper Infinium 203 Stretch fabric on rear-facing surfaces for greater stretch and breathability.
FEATURES: Taped shoulder seams in addition to top-and-bottom YKK Vision zippers that are covered for additional wind and rain protection. Zippered ventilation openings on the side of the chest and 3 rear pockets with a reflective panel keep you visible at night.
