The Giro Chrono Wind Vest uses well thought out details throughout the garment to make sure you stay warm while your body is still allowed to breathe. Using thin nylon, the wind vest packs down nicely and is extremely light weight, giving it a barely-there feel as you ride with huge benefits. It uses a back mesh panel that allows heat to escape while still offering protection from the wind. The front two-way zipper also allows for ventilation while still keeping more sensitive areas, like your neck, protected. An athletic fit ensures it fits nicely over heavily loaded jersey pockets while binding at the cuffs make sure the vest stays in place nicely and does not flap in the wind. The Giro Chrono Wind Vest is available in five sizes, Small – XX-Large. It is offered in the colors Charcoal and Flame Orange.
