The Soley Shield is made from the Highest quality optically clear, fog resistant PET-G plastic. Our multi-radius, full-face design is patent pending and maximizes protection, functionality and comfort while minimizing heat and fogging issues. <br> Many other companies use cheaper polycarbonate, which is less flexible and fogs more easily. Or use vinyl, which has poor optical quality, creates visual distortions, and has significant fogging. <br> Soley has been making medical devices since 2012, here in Indiana USA. We have an amazing experienced production team with an average of 6 years of experience making medical devices. We work with doctors around the country to provide great quality and service to all the patients we serve. <br>
