Thanks to its UF HybridShell fabric, a thermal, ribbed fleece material woven with a high density outer weave, the Q36.5 Essential Vest delivers wind resistance comparable to that of a traditional soft shell fabric while maintaining a very high degree of breathability. You will immediately appreciate the advantages on long descents where the sweat soaked jersey is able to wick through the vest and properly dry; an entirely novel sensation for riders used to the vests currently available on the market. The material has undergone a treatment before being woven for water resistance and fast drying times. Two slits for easily accessing the rear pockets of your jersey.
