First off - no need to apologize about repeating a topic. At this point, if everyone just did a search for past information rather than asking the question there would hardly be anything new written on these pages. That's not what campfire conversation is about IMHO.
For hearing protection at the range I double up with quality foam ear plugs then regular earmuffs.
For the field I use those banded ear plugs. The pros - light, inexpensive, I can hang them around my neck and still wear my cowboy hat. They may be rated in the 20's vs. the 30's, but definitely better than nothing at all. The cons - I always find a way to break off the tips every couple of years.
