What Our Gearhead® Experts Are Saying:"I’ve used the Alpha 150 Jacket on everything from freezing dawn rides to brisk shoulder-season spins. It breathes when I push hard, yet still blocks the chill perfectly. The fit is spot on, and those sleek wrist cuffs slide right under my gloves without bunching up."When winter’s cold starts to bite, the Castelli Alpha 150 Jacket keeps us rolling. Designed with an innovative two-layer system, the Alpha lets us manage airflow and warmth separately—no more getting clammy when the pace picks up or the climb gets steep.The articulated collar and soft cuffs keep drafts out while moving fluidly with us, whether we’re tucked into the drops or cruising an open stretch. And with Windstopper® 150 fabric at its core, we know we’re shielded from wind and damp roads while still enjoying an impressively mobile, comfortable fit. It’s our ticket to ride year-round, no matter how low the mercury drops.
