Fog Klear anti-fog cloth. Dry anti-fog cloth good for 200+ applications. Double-seal cloth storage system for added protection.
I've used the Nike Fog Eliminator cloths for years (for defogging my binoculars), but they seem to be disappearing from the marketplace. Bought the LensPen hoping it would be as good. Not quite. It's okay, but just not as effective overall. Maybe works better for cameras, but binocular eyepieces need something a little stronger it seems.
I'm very impressed, I have try lots of different options before, including the Nikon version, but LensPen was by far the best.
Used this on vacation a few weeks back, and it performed as advertised. When going from air conditioned room to very humid environment, fog on my camera lenses was expected.. this cloth left me amazed as it worked every time at quickly de-fogging my lenses!
