Any great success is built upon a strong foundation, and the new BE:1 Blackout Trek Base series is built to offer defense against two of the biggest obstacles in whitetail hunting: sight and smell. The Trek series utilizes fine Merino Wool bonded with Carbon Alloy(TM) for unprecedented odor protection, our Silver Alloy(TM) treatment to defend against bacterial growth, and our Fusix(TM) technology treatment for additional odor adsorption.
