After all that preparation of ensuring both you and your gear are scent free, it doesn't make much sense to step into a blind that smells like plastic. With Code Blue's Triple-X Ground Blind Treatment, we've packed 3 times the normal concentration of nano-silver so you can double down on your odds at being totally undetected in the field. Composed of a silver-based polymer, Triple-X adheres to the fabric of your blind allowing a scent-free solution for up to 60 days in a single application. Unscented 32oz. bottle.
