Q:
I know a lot of scopes claim to be fog proof but can anyone give me an actual brand that lives up to this promise? Every scope Ive had out in the heavy rain and sleet has always fogged up at some point

All scopes fog-up on the outside. There is no way to stop that. The scopes that claim to be fog-proof are usually fog-proof. A fog-proof scope will not fog-up on the inside because they are filled with nitrogen. So basically all scopes these days are fog-proof, but that means on the inside only. There are no truly fog-proof scopes if you don't want the outside to fog. (Even my Leupold VXII fogs on the outside.)

Right on Hjohn, I try to carry a dry piece microfiber cloth or lens cloth in my bag to wipe the outside of the scope when it fogs.

Take a tip from "scuba" divers and "spit" on the lens(outside) It does work. Even better keep the scope from MAJOR temp changes (inside/outside) by keeping the weapon in your truck,mud room, etc.
That should solve the problem.

All the tips above are right on. I've found Leupold to be as weather tight as any on the market.

4 years in Alaska and Leupold is the #1 seller so go figure!

I own two and used them both from minus 75 to a plus 120 and never had a problem!

Ultracoatings inc has a product you can rub on the outside lens that makes water bead and run off. It's better than rain X and much longer lasting. I use it on my Leupold VXIII's. The stuff is new and has not been given a name yet. I understand a large national company is negotiating for the rights to this stuff right now.
I hunted all over Alaska with 2 leupold VXIII's on my rifles and NEVER had a problem of any kind. Stayed wet 8 out of 10 days on Afognak Island in Nov 87.

I have hunted for three decades with Leupolds and no fog up on the inside EVER. They will all fog on the outide if you breath on them or bring them in a humid warm house from very cold outside temps. No problems with scopes but I did once exhale on my eye glasses though. It was about 10 below zero. I was buried in snow and coyote calling. The last time I saw him, a coyote was sneaking in at about 40 yards away. As I exhaled a little prior to pulling the trigger, my glasses fogged and I couldn't see anything. I had to wait until they cleared; however the next thing I knew, I felt his nose touch the barrel of my rifle. I jumped up and ripped my glasses off and started shooting when he was about 100 yards away and flying. I couldn't see squat and missed him clean. My brother who was watching wondered what on earth I was doing and couldn't believe that one got away.
