FinallyME,

Several years ago at a local army surplus store I found a great pair of heavy Army Ranger 200-300 weight fleece bid overalls "overpants" with suspenders and side zips and long front zip.

I don't use these backpacking but I do use on SAR callouts while waiting around base camp for next task and I use on car camping with BSA. They are the absolute warmest thing imagineable. Not good for hiking but do get used for right purpose.
