A water and wind resistant jacket or thermo regulating vest for cool, windy days Actually, the Pearl Izumi Men's Elite Barrier Convertible Jacket is both, quickly converting from a protective shell to a heat retaining vest in a matter of seconds with its zip off sleeves. Its Elite Barrier shell blocks the breeze, while shedding light showers and road mist. Direct Vent panels improve ventilation when you're hammering up steep grades and increasing your cadence on fast training rides. Highly visible after dark, the convertible jacket's 360 degree reflectivity keeps you safe when you're riding at dawn and dusk. Its full length draft flap seals out rogue gusts and sustained breezes from chilling your core. Other key features include a drawstring adjustable hem for a dialed fit, as well as zippered hand pockets for holding riding accessories and other items.
