I've had a set of these 10x30 binoculars for about 5 or 6 years now. I like them, but there are a few issues that I should address, and I'm hoping some of you all might have them figured out already. First, I need some decent lens covers. They came with this little cordura case, which lets in all kinds of dirt, bugs, and weeds and keeps them in there with the binos. I wouldn't need the case if I just had some caps that would cover the lenses. Anyone know where to find some? They also fog up a lot when I look through them in colder weather. What can I do to prevent that? Finally, can anyone recommend a really good lens cleaner? I've heard you shouldn't use windex on them. I want to get the glass CLEAN and keep it that way. Thanks!
