We built our 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.
