The Ear Band-It® Ultra Shark – is made from custom-designed, embossed neoprene on the inner side of the headband providing extra grip on the forehead, ears, and back of the head to avoid slipping during most types of water activity. It also contains 4.0mm 100% neoprene instead of 2.0mm-3.0mm neoprene blend that other headbands use. This gives the Ear Band-It® Ultra unparalleled strength and comfort. The unique shape of the Ear Band-It® Ultra is different than the Original Ear Band-It® headband and other swimming headbands. The ear flaps are larger, which increases the surface area, creating more grip and better coverage of the ear itself. Also, the bridge at the forehead has been widened, which adds strength, reduces the potential for tearing at this stress point, and increases skin contact surface area for better grip.
