The Fanatic Bib is the most advanced sound-suppressing fabric in the hunting world, built for warmth and windproof protection on cold winter days where stealth and body temperature are critical. A Berber fleece face silences the GORE-TEX INFINIUM with WINDSTOPPER Technology barrier for 100% windproof warmth while 133 g/m2 Primaloft Silver Insulation traps body heat. Low-bulk hems and full side zips allow you to step into the bibs in your stand without having to take your boots off, and they quickly and quietly allow you to dump heat when needed.
