I've used inner tubes, flip-ups and other scope covers for weeks in Alaska and other places. ALL will end up with condensation on the lenses in certain conditions, but in general I've come to prefer ScopeShields due to their quick one-point release (much like the original Uncle Mike's rubber band covers) and their protection of the rest of the scope.
But who cares what any one of us uses--UNLESS any one of us explains their specific reasons? Which hasn't happened all that much in this thread.
