A great winter cycling jacket requires materials and fabrics that ensure the comfort and fit a cyclist needs, but also the thermal, wind and weather protection needed to ensure you can perform. With a high thermal value, superior wind blocking, incredible fit, and water resistance, the Castelli Dinamica Jacket has been designed and developed for women. This is not a men's jacket with a women's cut, but a properly assembled garment that will move with you yet keep the cold and damp out, with high inherent breathability that will sustain you on the long training rides that will define your endurance and perseverance throughout the warm weather cycling season.
Castelli is employing premium thermal and wind blocking fabrics from the GORE-TEX INFINIUM line, which is focused on thermal, breathable, wind blocking over waterproof capabilities. The Infinium X-Fast product is used for forward facing blocking with a little more protection, while the piece overall features Infinium Windstopper, with a lofted fleece that retains heat and lifts moisture away from you next-to-skin and mid weight layers. The entire piece does have DWR treatment for water resistance but it is not designed for lengthy, heavy rain. The combination of blocking and thermal properties means you can endure cold for long periods, while the premium moisture transfer properties ensured by the Gore textile membrane technologies will keep you drier even with high intensity efforts and long, lower intensity rides in the bracing cold.
Of course, their attention to detail and design features that truly matter is what drives the design team at Castelli to perfect their garments and the Dinamica Jacket is no exception. The cut is anatomic for a generalized women's form, with a tapered fit, a little more suppleness around the chest, and a soft, brushed fleece collar. The true performance winter cycling cut reduces bulk and length up front, but giving ample coverage in the rear. The panels of the piece allow it move with you yet still retain the closer fit needed for the moisture transfer properties to be most effective. Three rear pockets are easily accessible for storing your necessities, and smooth sliding, but secure YKK Vislon zipper can be quickly manipulated with gloves on. Finally, and of equal import as the rest, there are excellent reflectivity zones on the front and back to keep you as visible as possible in low-light conditions.
