High grade waterproof bag that revitalizes your shoes and gear, extending their usability. It works by absorbing moisture, neutralizing odours, and protecting against unwelcome smells, moisture, and bacteria. Just place your items in the bag and let the freshener work its magic. The full effect lasts 2 years but your freshener bag keeps working long after that. The scent will gradually fade over time. Turn inside out and recharge in the sun a couple of times per year to rejuvenate the effect.
