Flip up caps - Hawke Sidewinder 4-16x50

[Adop]

I just purchased a Hawke Sidewinder 30 4-16x50 SF and am looking for a somewhat weather proof pair of flip up scope caps for hunting (nothing crazy expensive). The Hawke ones are not weather proof and very expensive.

What do you use?

I use the clear Butler Creek Blizzard caps. Being clear, I don't have to flip them when hunting if a quick shot is needed, and if they fog up from heat or breath I can open them to get to clear glass. Also, they are water tight.

They are hard to find in stores, so I buy them off eBay, based on the measured size. My Arken 4-16X50 has an outside diameter of 2.325" and needs a #10 (size is the last two digits of the ring model number). Here's the Blizzard measurement guide.
