The Columbia Men’s Eager Air Interchange Jacket is an everyday winter favorite, thanks to its three coats in one design. Wear it as a waterproof shell, a cozy fleece coat, or combined the two as super warm and cold wet weather jacket. From winter snow, to spring rains, to chilly fall days, and everything in between this is a great year-round coat. The shell is crafted of our Hydroplus waterproof nylon, a rain jacket that keeps its promise of wet weather protection. The fleece jacket features is made from heavy-weight 250g filament fleece, and is so warm and cozy, and provides a collar that can be worn up, or down. Together, the two jackets form a three point interchange system that includes a storm level hood with soft chin guard, two zippered side pockets, and adjustable elastic cuffs to seal the cold mix out, and keep the warmth in. This men’s interchange jacket is available in multiple colors and sizes. Available in extended sizing. Regular Fit. To ensure the right fit, please 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 sleeve. 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.
