What Our Gearhead(R) Experts Are Saying:"I pulled this out the moment the mornings started getting genuinely cold and kept pushing the same hard efforts without missing a beat. The breathability held up on every climb, and the splash tail kept spray off my back on a wet ride without me thinking twice about it."Dropping temperatures shouldn't mean dropping intensity, and Castelli built the Sweetspot Jacket for the rider who refuses to let cooler air slow them down. We love how the Ristretto fabric technology holds warmth early in a ride, then breathes hard the moment the effort spikes, so the jacket keeps pace no matter how hard we push. Three lie-flat pockets keep gear secure and low-profile, with a fourth zippered pocket dedicated to valuables that need a little extra security. An engineered waist with an ergonomic splash tail guards against wheel spray, so the only thing left to focus on is the effort in front of you.
