The Sitka Fanatic Jacket is the total package for ultra-quiet warmth, utilizing the most advanced sound-suppressing fabric in the hunting world. Built with deadly quiet high-loft Berber fleece face, an ultra-quiet GORE-TEX INFINIUM™ with WINDSTOPPER® Technology barrier for 100% windproof warmth and PrimaLoft® Silver Hi-Loft Ultra insulation for the coldest days in the stand. Body-mapped construction optimizes the draw cycle for bowstring clearance along with a reduction in bulk in the draw arm to minimize noise and keep your arrow flight true. The Constant-Connect SITKA® Safety Harness Port eliminates the need to disconnect from your harness when adding or subtracting layers. Hands down, this is the quietest hunting jacket on the planet.
