Fresh Helmet, Equipment, and Boot sacks were designed with athletes in mind! These sacks works to soak up moisture and neutralize unpleasant odors caused by everyday use! After each ride, simply toss your helmet sack into your helmet, your equipment sack into your tack trunk, and your boot sacks into your riding boots or shoes and you will have Fresh, dry, and odor free helmets, equipment, and boots the next time you ride! Once a month or so, regenerate your fresh helmet sack by microwaving it on low for 2 minutes (remove it every 30 seconds and give it a good shake) or sit it in the sun for 12 hours (you can leave it on the dash of your car while mucking stalls or hand grazing your horse)! Don't forget that you can use these at home too (for example, in your tennis shoes, cowboy/cowgirl hat, gym bag, near cat litter boxes, etc)!
