The updated Sitka Big Game Open Country Mountain Vest features a two-way stretch and deadly quiet brushed Polyester face over the new 3-Layer GORE-TEX INFINIUM™ with WINDSTOPPER® Form Fit Technology. The combination provides light and extra durable protection on windy days and in light precipitation. The zippered chest pocket provides sanctuary for necessities, and two zippered hand pockets are designed to fit above a backpack’s waist belt without bunching when carrying a heavy pack.
