Abstract
An article of headgear that has a head-covering article, a lens moveably attached to the head-covering article, and a seal attached to the lens, the seal comprising a first polymeric material and a second polymeric material, the first polymeric material having a greater tensile modulus than the second material. In an exemplary embodiment, the lens is moveable from a first, lowered position to a second, raised position, and when in the first, lowered position, the seal sealingly engages the head-covering article. In some embodiments, the tensile modulus of the first polymeric material is at least about 5× greater or even about 10× greater than the tensile modulus of the second material.
