Butler Creek non-see thru model. Throw a wrap of electrical tape around each one and go. I've only broken two of them in 20 years of using them and I've lost one prior to taping them. I have had a couple of instances of fogged lenses, but it has been rare. Can't go wrong with them IMHO. They are quick to open/close, leave them open if it's nice out, close them and pop open prior to a shot if it's snowing/raining, can't forget them or lose them, if they do break you're only out a few bucks.
