I bought a pair of these bibs in 2005 to be worn as a do-it-all outer layer for wear in the mountains while performing law enforcement duties,including crawling over rocks,through brush,over and under vehicles while winching people back up onto the roads after they had slid off in the snow. I bought them larger that needed to allow for wearing mid-layers as needed depending on how warm or cold it was,and still allow me to wear by body armor inside to keep it dry. The full length chest to lower back
waterproof zippers come in handy for when nature calls...I don't even have to remove my gun-belt from around my waist.The side zippers from hip to ankles make it easy to allow for built up heat to escape and to stay cool inside my patrol vehicle. The elastic cinch-cords afford a quick and easy means to snug the pant legs tight around the ankles of your boots when in deep snow or when on snowshoes,skis,or crampons.With the small grommets on both the inside and outside lower edges of the legs,attach a piece of elastic cord to go under the arch of your boots,and you are as close as you can get to a gaiter.They're going on seven years of full-time winter use,and they look almost new. Clean and waterproof them with Nikwax or similar products designed for gore-tex as needed, and they will as warranted,last a lifetime.
