After 20 years of producing the leading scent control system with activated carbon, Scent-Lok Technologies has developed a formula that gives hunters an even better advantage in the field. The same drive, dedication and innovative spirit that launched their most effective scent adsorbing technology has now produced the ultimate activated carbon scent control technology, Carbon Alloy™. Scientists worldwide recognize that activated carbon has long been the best adsorbent for human odors. Scent-Lok's new Carbon Alloy™ sets a new standard by adding other components to their activated carbon to enhance the ability to adsorb odors to extreme levels. Carbon Alloy™ will increase the spectrum of adsorption by its ability to target human specific odors.Their new additive is Zeolite. Zeolite adds adsorptive range to activated carbon by adsorbing smaller odor molecules, such as ammonia, better than carbon alone. Another new addition is Scent-Lok's new treated activated carbon. Scent-Lok's new treated carbon can adsorb up to three times more hydrogen sulfide, a cause of strong breath odor, than untreated carbon alone. The combination of activated carbon, treated carbon and zeolite extends the scent control spectrum beyond activated carbon or zeolite alone. The method used by Scent-Lok® to incorporate the highly effective concentration of Carbon Alloy™ components into the fabric provides odor protection for many seasons, withstands repeated washings and can be reactivated in a house hold dryer to work again and again. Scent-Lok Technologies provides an unconditional written guarantee backed by years of service and success in the field for all products. Scent-Lok® is making Carbon Alloy™ and you the deadliest combination in the field.
