When we are riding in less-than-ideal weather, having a cycling jacket that can do it all is a must-have. The Castelli Alpha Ultimate Insulated Jacket is waterproof, insulated, and performance-oriented to keep us performing our best no matter the weather. The Polartec NeoShell 4-way stretch fabric blocks the moisture and wind while moving with our body to give us a high-performing jacket. Polartec Alpha insulation keeps us warm in cold conditions, and critical seam taping ensures no water will get through the cracks. Three stretch rear pockets and a side zippered pocket store all our essentials, and anatomically-shaped cuffs integrate with our gloves to keep cold air out of our sleeves.
