Base Fresh is a deodorising product specially designed by the brand Nikwax to treat your technical underwear and wool. This effective deodorising softener prevents your technical underwear from accumulating bad odors, providing them with efficient moisture-wicking performance once again. Indeed, regular detergents and softeners can inhibit the moisture-wicking properties of technical underwear. Base Fresh allows you to revive their moisture-wicking power, so your technical underwear smells better and continues to protect you during your outdoor activities.
