What Our Gearhead(R) Experts Are Saying: "I like the PRO Barrier Vest because it disappears when you don't need it and makes a huge difference when you do. It blocks wind really well, especially on early descents, and the two-way zipper is perfect for grabbing snacks or ventilating on climbs. It's one of those pieces I end up carrying almost every ride."We turn to the Pro Barrier Vest from PEARL iZUMi when cool mornings, windy ridgelines, and shifting weather call for a simple layer that keeps the ride smooth. This vest brings lightweight protection that feels nearly weightless on the bike yet instantly shields the core from sudden gusts or patches of drizzle. With a sleek, compressive fit, it sits comfortably over a jersey without flapping, letting us move easily through long miles or spirited group rides. A two-way zipper lets us vent heat quickly or reach jersey pockets without slowing down, and the packable design tucks into a tiny bundle when the day warms. Reflective elements boost visibility on early starts, and the PFAS-free DWR helps the fabric resist light moisture. Whether we're heading out for a sunrise spin or gearing up for an all-day road ride, this vest adds just the right amount of confidence without adding bulk.
