The whole product weighs only 30G/0.6LB, long time wearing will not have any burden. In order to solve the situation that the scarf is easy to slip off, we adopt the design of hanging ear, which is less pressure on the ear and more stable to wear, not easy to slip off. Compared to traditional face-fitting bibs, this one of ours has a relatively loose design, which is less constricting to the face and increases air circulation between the face and the bib, reducing the feeling of stuffiness. Both the front back and sides are able to cover your skin perfectly, opening up a 360° surrounded protection for your skin, easy to protect against UV rays, sand and dust. Our bibs are made of high sun protection ice silk fabric with UPF 50+,UVA 0.64%, which effectively reduces the damage caused by prolonged exposure to the sun. Meanwhile, the mesh fabric is spliced at the mouth and nose, which makes you breathe more freely.
