Sitka Gear Incinerator Jacket, Optifade Elevated II, 2XL - 50026-EV-XXL A virtual walking sleeping bag that?s 100% waterproof, the Incinerator Jacket brings two crucial firsts to the whitetail world: It is the first whitetail jacket ever to be insulated with warm-when-wet PrimaLoft? Silver Down Blend, and it?s the first jacket with a waterproof safety harness pass-through port. The 2-layer GORE-TEX? membrane is wrapped with a perceptibly quiet, lightly brushed face fabric. internal cuffs seal off heat leakage, and a YKK waterproof front zipper ensures you?ll stay dry.
