Gilets are handy for the shoulder seasons when the temperature drops but it isn't quite cold enough for a winter jacket. By keeping your core warm and pairing with your favourite jersey and arm warmers you get a cosy outfit with maximum freedom of movement. Perfect for bright but chilly autumn days. Castelli have used new Gore-Tex Infinium fabric for their Perfetto Ros vest, a new style fabric that is: Totally windproof, so no matter how cold it is or how fast you're riding, that chilly air will be kept out Highly breathable, so you can be warm without being drenched in sweat. Water resistant. In fact, Infinium is almost waterproof it's so good. Stretchy. The Perfetto vest moves with your body for comfort and performance. Infinium is used on the front of the vest to block cold air, while on the back a lighter Nano Flex fabric breathes even better and offer water resistance against rain or spray. The dropped tail ensures the vest doesn't ride up while the 2 pockets and pump sleeve keep your essentials to hand without moving around. Altogether, the Perfetto vest is as close to the perfect vest as you're likely to find. Ideal for training or cold weather racing, or any riding where you need extra warmth without the bulk of a jacket. Please note the sides and back of this item are black and not pink as pictured.
