Ohio7x57: I started using "scope covers" many decades ago with the rubber band attaching KA-RAM-BA scope covers - still have a couple on vintage Hunting Rifles.
Then along came the Butler Creek style scope covers that I started using and they work well for me - they were a blessing on my many Alaska Hunts for Mt. Goat and Black Bear.
Even use them on my spring and summer Colony Varmint Rifles - dust you know!
This fall on my Antelope Hunts I used the newish Leupold "neoprene" one piece cover and it worked very well - I have used these neoprene covers in the past on several occasions.
Toss-up which I like better.
Hold into the wind
