Masking your scent isn't enough. You need to eliminate your scent. Dead Down Wind Evolve Field Spray uses advanced enzyme technology to eliminate a broad range of scents which can come from your skin clothing and hunting gear. Evolve is made with natural and healthy enzymes that attack odor causing bacteria at a molecular level while leaving good bacteria behind. It is never made with biocides so you can be confident your skin, clothes, and gear are safe. Simply spray on your jacket, gloves, hats, coveralls or any other hunting accessories you will have in the field to be hidden all day.
