This is an amazingly versatile jacket. It is a windproof textile jacket for cool days, but fold down the inner windproof panels on the chest and back; open the full length arm vents and side torso vents, and you have maximum air flow on hot days.
An additional removable zip out H20 Blok® waterproof liner means you can handle wet weather, and the included removable thermal EverHeat® liner keeps you warm when it gets cold. SAS-TEC® CE certified visco elastic armor is used in the shoulders and elbows. From touring in cold wet climates, to commuting in hot humid places, the Yosemite jacket will handle it all.
