IdahoElkHunter: I gave up on the Butler Creek scope covers for Big Game Hunting some years ago - they just do not remain closed when I need them closed - this is aggravating when Hunting in rain, snow, sleet, hail and in dust thrown up by ATV travel etc etc etc! I still use them for the less critical/demanding Colony Varmint Hunting situations and while travelling around in luxury vehicles for lens protection. I now use (went BACK to!) the old style Ka-Ramba scope lense covers with the elastic flip off/retaining system when bad weather and Big game are on the menu. I would be very interested in trying one of the "Scope Shield" type scope covers with elastic retainer - first test would be to see how long they stay affixed (in position to protect the scope lenses from rain, snow, sleet and dust) while Hunting with Rifle slung over the shoulder.
