With the Whirlibird Interchange Jacket from Columbia, you get the benefit of 3 jackets in 1. One layer being a cozy, water repellant zip-in liner that features Columbia's Omni-Heat Thermal Reflective Technology. The next being a waterproof/breathable Omni-Tech, critically seam-sealed outer-shell, and then the combination of both allowing you to stay warm, dry and comfortable in ANY winter weather conditions. A removable, adjustable storm hood offers additional warmth in cold weather while the underarm venting is perfect for when things start to heat up and you need some air flow. An adjustable, snap back powder skirt and drop tail hem ensure no snow gets inside, allowing comfort for long days out on the mountain. The Whirlibird has multiple pockets for holding on to small items and necessities, including a goggle pocket and an interior security pocket that is perfect for valuables. The waterproof center front zipper makes sure that no moisture seeps in and adjustable cuffs allow you to customize your fit for unmatched comfort.
