No little red spring loaded buttons on my Butler Creek Blizzard caps, just two little black tabs at the 10 and 2 position that you lift with a finger. I’ll keep them down walking to my stand to keep the dirt out, but they are open unless there is snow or rain falling. Those see through clear windows in the caps would work in a pinch to shoot with, so if it wasn’t for that feature alone, I probably wouldn’t buy them.
+1 exactly how I use them. Yes I've broken some, but they are cheap. I like not having to keep track of them when i flip them up. Unlike a bikini cover.
