I have only used a bikini cover on my scope but after hunting a couple times in the rain this year I think I want to upgrade to some caps.

What is everyone using?

I now have a Nikon Monarch (3-9) and a Leupold VariX II 2-7.

It looks like Butler Creek is the go to? Leupold seems to be hawking the Alumina covers - but they're pricey!!

Thoughts?
