The ultimate rain jacket that also works well in cool dry weather. Designed to maximize ventilation options so that the user can adapt to changing terrain and environmental conditions with 7 venting options. The cuffs that have a gusset and special lycra fabric that can be opened to scoop cooling air up the arms and out the back vent. Two 7" (18 cm) pit zips can be opened for added ventilation as needed. The front zipper can be opened from the bottom as well as the top. This bottom pull zip allows the wearer to regulate temperature of the lower back without turning your jacket into a parachute. The back vent works with these six front vents to move hot air away from the body - keeping you cool prevents sweat build-up on climbs and when you are working hard.

FABRIC eVent fabric is a highly breathable waterproof fabric, and its also very expensive. In this case you get what you pay for - eVent is very durable and works super-well for high energy outdoor activity. Waterproof: The industry standard for waterproof testing is the water column test. This measurement is accomplished by measuring the milimeters of water that can be held by the fabric without leaking. The minimum requirement is 1000mm for a fabric to be considered waterproof. Breathable: MVTR (Moisture Vapor Transfer Rate) is measured in a chamber, divided vertically by the fabric being tested. A dry atmosphere is in one chamber, and a vapor-saturated atmosphere is in the other. A 24-hour test is run to see how much moisture passes through the fabric from the saturated chamber to the dry chamber.
