WindKill does more than just block the wind; the 3-layer laminate fabric keeps water from soaking through. Not every day on the marsh is going to be bone-chilling cold. The Dirty Bird WindKill jacket gives you an option for warmer weather, but will keep you from getting soaked and wind chilled. The watertight cuffs are a boon when you're setting or retrieving your decoys - allowing you to dip your forearm into the water as if you are wearing a dry suit. Angled pockets located primarily on the chest allow you to warm your hands or access calls, shells, chokes, or a granola bar without having to dig around in pockets covered by chest waders.
