What Our Gearhead(R) Experts Are Saying: "This is one of my go-to vests for big days out. The Polartec Alpha insulation keeps me warm without overheating, and the two-way zipper makes it easy to vent or grab my jersey pockets mid-ride." When long rides call for versatile layering, we zip into the PEARL iZUMi Expedition Pro Alpha Vest. Built with 60g Polartec(R) Alpha(R) Direct insulation, it offers active warmth that dumps heat before sweat builds up, so we stay comfortable grinding uphill and descending into headwinds alike. A lightweight Toray shell balances wind protection with breathability, while stretch side panels let excess warmth escape and keep the fit streamlined. This vest is made for the demands of bikepacking and all-day rides, with smart details like a two-way YKK zipper for quick ventilation and easy access to rear jersey pockets. Secure chest and back pockets keep essentials close, and BioViz(R) reflective accents provide peace of mind after sundown. With PFAS-free water resistance and recycled content, it's a piece we feel good wearing wherever the adventure leads.
