The average temperature during the peak of the Midwest whitetail rut is 36.5°F, so it only makes sense that the Zone7-Versa series fits this temperature range. The Code of Silence Zone7-Versa Jacket is built with no-nonsense technical specs galore, but without the frills that often get in the way. Berber-Wool on key areas is the quietest fabric used in the hunting industry today, giving you absolute silence when you need it most. And Berber-Fleece paneling reduces friction and deters burrs from clawing their way into you. Antimicrobial 3X-Tricot lining throughout means you won't be sniffed out by wary game. Well-fitted articulated design gives you hinder-free climbing, shooting and and moving about.
