What Our Gearhead(R) Experts Are Saying:"The Amplify Thermal Jersey is my go-to for those cool, crisp mornings when a lightweight jersey isn't quite enough. The fleece-lined body traps warmth while the stretchy sleeves keep me moving freely. Plus, the vibrant design always gets me compliments on the road."We're always searching for that perfect balance of warmth, breathability, and performance when the temps start to drop, and the Amplify Thermal Jersey nails it. Its mid-weight fleece construction keeps us cozy without feeling bulky, while the sleek cut and stretch panels move with us on every climb and descent. Castelli built this jersey with thoughtful features like three rear pockets to stash our fuel and an easy-sliding YKK(R) Vislon(R) zipper for quick ventilation when the effort ramps up. The vibrant design is as eye-catching as it is functional, making every chilly ride feel like a little more of an adventure.
