I don't actually own a set of these bibs because I had to send mine back.  I wear a 36" jean and ordered these at 38" to accomodate under clothese.  Too small.  I couldn't even button the side snaps.  I gave it three stars because it is very nicely and sturdily stitched and by all appearances should be a durable and warm set of bibs.  -2 stars for inaccurate sizing.
