I have a pair of quilted Carhart bibs that are warm but are really stiff to put on and wear. They're heavy too. I'm soon 80 and have bad shoulders so I need help even getting them on. I wear them when working in the woods, plowing snow, or walking around the woods checking trail cameras. I see ice fishermen and some wrecker personnel wearing coveralls that look to be warm and more flexible. I'm wondering if any of you have experience and recommendations?
