This award-winning rain jacket features a performance blend of waterproof-breathability, strategic venting, and advanced wicking technology. Plus, it packs down to almost nothing, so it’s easy to stow and deploy at a moment’s notice. The technical details of the Columbia Evapouration Jacket are what make it so versatile and special. Crafted from 100% nylon with our EVAP Tech woven material, this rain jacket is guaranteed to be waterproof; the seam-sealed construction and vented underarms keeps you dry while blocking any cold wet wind. A drawcord adjustable storm hood stop the rain from getting in, while zippered pockets are featured on each side to secure your small items. Adjustable, velcro cuffs and an adjustable drawcord hem help give this jacket a customizable fit. Columbia's Evapouration Jacket is available in a range of sizes and colors. Extended sizing available. Regular and Active Fit. To ensure the size you choose is just right, utilize our sizing chart and the following measurement instructions: for the sleeves, start at the center back of your neck and measure across the shoulder and down to the wrist. If you come up with a partial number, round up to the next even number. For the chest, measure at the fullest part of the chest, under the armpits and over the shoulder blades, keeping the tape measure firm and level.
