Castelli Estremo Men´s Jacket: Conquer the Deepest WinterWhen the temperature plummets and biting winds threaten to end your ride, the Castelli Estremo Men´s Jacket is your ultimate defense. Engineered as Castelli´s warmest jacket, the Estremo is meticulously designed for cyclists who refuse to let extreme cold dictate their training schedule. It provides an unparalleled level of warmth and protection, allowing you to ride in comfort through sub-zero conditions without the burden of excessive layers. Face the harshest elements head-on and maintain peak performance with this pinnacle of winter cycling apparel.The core of the Estremo´s incredible performance lies in its intelligent dual-layer construction. The outer shell is crafted from the highly effective GORE-TEX INFINIUM™ WINDSTOPPER® fabric, creating an impenetrable barrier against windchill while offering excellent water resistance to fend off road spray and light precipitation. This outer layer is separated from a soft, brushed fleece inner layer, which traps a significant amount of air to provide exceptional insulation. This two-layer system not only maximizes warmth but also excels at moisture management, allowing perspiration to escape so you stay dry and comfortable from the inside out, even during intense efforts.Functionality is built into every detail of the Estremo Jacket. A unique double-zipper system, featuring a smooth-gliding YKK® Vislon® zipper on the outer shell, allows you to open the external layer for ventilation while keeping the insulated inner layer closed. This provides granular control over your core temperature as your effort level or the weather changes. The high, soft-lined collar seals out drafts from your neck, while the innovative double-layer cuff design creates a perfect seal with your winter gloves, eliminating any cold gaps. For practicality on long winter miles, the jacket is equipped with three spacious rear pockets for easy access to nutrition and essentials, plus a secure zippered pocket for keys and valuables. Reflective panels are strategically placed to enhance your visibility to others in low-light conditions, adding a crucial element of safety to your winter rides.---Technical Specifications* Product Name: Castelli Estremo Jacket* Gender: Men* Recommended Temperature Range: -5° to 5°C / 23° to 41°F* Fit: Neutral Fit (Close-to-body without being restrictive)* Main Fabric Technology: GORE-TEX INFINIUM™ WINDSTOPPER® 150* Insulation: Separate brushed fleece inner layer for maximum warmth* Zipper: YKK® Vislon® front zipper for easy sliding* Cuffs: Double-layer cross-wrap closure for a perfect glove interface* Pockets: 3 rear pockets, 1 zippered side pocket for keys* Visibility: Reflective panels on front, back, and sleeves for 360° visibility* Weight: 522 g (Size L)
