The Sitka Gear Men's Fanatic Vest is the quietest top to warm your core without hindering torso mobility when Whitetails bolt at the mere rumor of noise. The upgraded textile and deadly quiet Gore-Tex Infinium with Windstopper Technology allows you to move with more confidence by cutting the audible engagment distance in half, and core warmth is enhanced with compression-resistant PrimaLoft Silver Hi-Loft Ultra insulation. The newly integrated Constant-Connect Sitka Safety Harness Port ensures quick donning and doffing as temperatures fluctuate in the stand, allowing you to add or subtract layers without disconnecting from a harness.
