Optrel® Front Cover Lens, 5-Pack

I was relieved to find these lenses fit my e640 helmet perfectly. The pack gives me a good supply for swapping out the dirty cover often.

These five lenses fit my e670 without any fuss. I've only used one so far, but it's held up well through a few long welding sessions. Wish the pack came with a spare gasket, though.

The spares themselves are solid and the 5-pack is good value. My only gripe is the packaging is a bit awkward to open without risking a scratch on the first lens, but that's minor.
