ConQuest Orange Stink Stick Scent Wicks are a premium fiberglass scent wick that allows more air to flow through and carry off the scent. Maximum scent carry means maximum possibility of success! A tapered thread keeps the air out completely and the scent fresh, o-rings are outdated. This leak free design means your pack is safe from the scent that is awful 99 percent of the year, and oh so good that 1 percent of the year. This wick will work in freezing temperatures, to keep them bucks rollin. This new rugged design means year of use.
