The EQUIPE RS JOHDAH Ultraz Winter Jacket S11 EVO is a winter cycling jacket built around a gilet that keeps working after the shell comes off. A DIAMOND Medium softshell covers the front and upper sleeves, blocking wind while holding a racing fit down to 17. 6degF. Unzip it during a hard climb, and the built-in LITHIUM Medium gilet keeps the chest warm on its own, while dual valveTec Diffusor valves on the shoulders keep pulling moisture out even when the shell stays zipped. What Our Gearhead(R) Experts Are Saying:"I unzipped the shell halfway up a climb in the low 20s, and the gilet alone kept my chest warm the rest of the way. That's the first winter jacket where dropping a layer didn't mean gambling on staying warm."
