What Our Gearhead(R) Experts Are Saying:"I wore this on a ride that started cold and stayed that way for a few hours, and never felt the need to peel it off. The front blocked wind on every descent while my back stayed breathable the whole time. This is the vest I grab whenever the temperature won't commit to warming up."Some rides never fully warm up, they just settle into a steady chill that sits on your chest the whole way through. The Castelli Perfetto 2 Vest handles that kind of day without overcomplicating things. Windproof coverage across the front cuts straight through the part of the ride that actually gets cold, descents, exposed ridgelines, long flat stretches into a headwind, while the stretch woven back keeps you from overheating once the effort builds. Three lie-flat pockets keep essentials secure with an added security lip, so nothing bounces loose on rougher roads. A top- and bottom-opening zipper means you can vent from either direction depending on what the moment calls for. This is the piece built for the rides where the temperature never quite makes up its mind.
