Best out there - Weaver Polar Caps

These look much nicer than Butler Creeks. They are thinner/tighter-fitting and look high quality -- as long as you keep your eyes and hands more than a foot away. However, they are just as cheaply made when you look close. Still, they are the best availible. I recommend the clear ones: the polar color thing only makes them hard to see through.
Pros: Look nice; see through, the rubber stretches to fit a wide range of scope sizes
Cons: cheaply made
