Washable, cheap, baggy, wind resistant wool pants. Where does one get such a thing?
I'd really like some.
Also, cheap wool bib shorts without pads and with a low front would be nice.
That would be the 1950's. Or a suit store.
Wool ain't cheap (not anything that will last, anyway) and nobody that I know of makes unpadded wool bibs. You just aren't looking for realistic things. While you may have some luck knocking around thrift stores, those items are going to be difficult to impossible to find.
