Weather is no match for this 3-in-1 jacket system, built with a waterproof-breathable, fully featured shell, and a warm insulated zip-in liner. Wear them together or apart—either way, you’re prepared for anything. The shell is crafted from our Generation Dobby nylon fabric, a jacket that keeps its promise of wet weather protection. The Thermarator insulated inner jacket is lined with our signature Omni-HEAT thermal reflective lining for the perfect warm and cozy. Together, it’s a three point interchange system that includes an adjustable hood with soft chin guard, two zippered side pockets, an interior security pocket, and adjustable sleeve cuffs. Three jackets in one. 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.
