Review on S8565 Bionic Uncoated Polycarbonate: The Ultimate Replacement for Enhanced Durability by Paul Hyde

Excellent for cutting and grinding with cutting tools and blades. It scratches easily, so it needs to be protected when not in use. I have this in one helmet and clear in another so this is used for specific projects where you need good protection and a wide field of vision. You still need clear goggles as sometimes sparks will ricochet off the inside and hit you in the face. Not cheap but I will buy more if needed.
