Castelli Pro Light Wind Cycling VestThe Pro Light Wind Vest is designed for those riders who need a little extra warmth when you head out in the morning before the day warms up. Since Castelli knew this vest would spend a lot of time in a jersey pocket, they made it as light and small as possible. It weighs just 81g (large) which is about the same as two energy gels. It also takes up about the same amount of space in a pocket. The back of the vest is mesh while the front is constructed of low-permeable woven poly fabric that keeps the wind off without letting moisture build up. With the Pro Light Wind Vest, you will never need to underdress again.FeaturesImpossibly light-weight and compact wind vestPrinted woven front and shoulders with low air permeability to block wind while remaining breathableMesh back for full breathabilityYKK Vislon zipper for easy opening and closingWeight: 81gRATINGWindproofWaterproofInsulationBreathabilityLightweightSizingJersey SizeSmallMediumLargeExtra LargeXX LargeXXX LargeChest36"37.5"39"41"43"45"Waist31"33"34.5"36.5"38.5"40.5"Castelli Sizing InfoCastelli products are aggressively cut and are meant to fit optimally in the riding position.
