Got my new FroggTogg bib overalls. They are much beefier (double walled, Tyvek type material on the inside, plastic on the outside) than my original pair. Fit tighter too but I'm used to the huge 4XL, not these 3XL--they do fit over jeans on me but probably not chaps. They have zippers down the front and the sides below the knee. Unfortunately this all means they're much bulkier. I guess I'll keep my older, lighter ones around for warm weather trips (for occasional rain) and take these newer ones when rain and/or cold are much more certain.
