The o.b.® ExtraProtect Super+ Comfort Tampons for very heavy days combine two leading tampon technologies to provide ultimate leak protection within the o.b.® range. The extra protective wings gently unfold to capture fluid that may leak past regular tampons. The unique Dynamic Fit™ technology with interlocking grooves helps distribute fluid efficiently inside the tampon. Additionally, the o.b.® ExtraProtect Tampons are gynecologically tested, contain a 100% plant-based tampon core, and are free from harmful chemicals, chlorine bleach, and perfume.
